Can you access the fault history in an ATS46 softstart using ModBus?

Issue: Can you access the fault history in an ATS46 softstart using ModBus?
 
Product Line: ATS46
 
Environment: All
 
Cause: N/A
 
Resolution: from the Global Help desk;
``You can access by ModBus with W4090 (from 1 to 4) for the fault number, the value is in W4069 and W4091 is used by the ATS to Recall the fault.``

What I think this means is that if you put a value of 1 in word 4090, the most recent fault will be reported in W4091. If you put a 2 in 4090, you will read the next oldest fault in 4091. 4090 is used as a pointer, and 4091 is used to display the value that is pointed to.

Can I poll 6 Digit Modbus registers with Telepace Studio?

The MSTR and MSIP use a block of registers to store their configurations.

If the MSTR block uses register 41001 in the SCADAPack as it's configuration start register, then :

41001 = Comm port number

41002 = function code

41003 = slave controller address

41004 = slave register address

41005 = master register address

41006 = length

41007 = time out in 0.1s increments

Trying to configure the MSTR block in Telepace prevents you from putting in a slave register address greater than 49999.

Using a PUTU block, you can put an unsigned integer in the range 40001-65535 into register 41004 to indicate the slave register address. It appears as though the program will take the value in register 40004 and subtract 40001 to determine the holding register offset that gets sent in the actual modbus message.

For example, using PUTU to put a value of 50010 into register 40004 would then cause the MSTR block to poll for a holding register with an offset of 10009 in the message which would correspond with a 6 digit address of register 410010.

The largest unsigned integer you could put into register 40004 would be 65535, which would correspond with a 6-digit modbus holding register of 425535.

When polling dual registers in InfraStruXure Central 6.0, both registers must be polled together.

Issue:

When polling dual registers in InfraStruXure Central / StruxureWare Data Center Expert, both registers must be polled together.

Product Line:

InfraStruXure Central / StruxureWare Data Center Expert

Environment:

Modbus communications

Cause:

Modbus registers are limited in size, which limits the values they can store and return to a BMS. Unsigned values can not exceed 65535. Because some values returned by ISXC may be greater than this maximum value, we have created the ability to use 2 registers together as a pair to allow for this larger output. If you choose to configure 31001 as a dual register, it will encompass 31001 and 31002.

Resolution:

When polling these registers, poll both 31001 and 31002 (or whatever register pair you have set up this way) during the same poll. Failure to do so will return invalid results.

Starting Register number in Modbus Read functions

Goals and Symptoms

When performing Modbus read commands, it is important to apply the right starting register address in the read function. Otherwise, the wrong register will be accessed from the meter, giving unexpected data for the meter parameter being read.


  • Meter is functioning as expected. The front panel values for voltages and currents are within expected ranges for the system being monitored. However, modbus read functions from a master station (e.g. a PLC) give values that do not correspond to the front panel values.

Facts and Changes

Modbus, modbus rtu, function read, modbus map, holding register, staring register, function 03, modbus read packet

Causes and Fixes

Cause
One probable cause would be that, the modbus function read command is not pointing to the right registers. The modbus protocol requires an offset to be introduced in the starting register address when reading the slaves register.

Resolution

When reading the meter parameters, the Master must send the device a Read Holding Registers packet. This packet must specify a start register and the number of registers to read. When the function read is received, the slave responds with a packet containing the registers in the range defined in the read request.

However, consider the 3710 Modbus map, which states that according to the MODBUS protocol, in response to a request for address 4xxxx, the master reads register xxxx-1 from the slave (3710). For example, a request for register 40011 returns register 10 from the slave.

What does the above statement mean? Why is an offset required?

Holding registers, by default, are defined the 4xxxx range, the first holding register staring at 40001. The starting register in the read packet is, on the other hand, numbered from zero. Hence, the start register zero automatically points to holding register 40001, starting register one points to holding register 40002, etc. The fact that the first holding register is 40001 and not 40000 explains the offset that needs to be introduced in the starting register number.

Hence, considering the 3710 Modbus Map statement, if the Master needs to read register 40011, then the corresponding starting register that needs to be put in the read function would be 10 (0A hex) since register 40011 is the register 10 from the first holding register, 40001:
40001 > Start register 0
40002 > Start register 1
40003 > Start register 2
40004 > Start register 3
40005 > Start register 4
40006 > Start register 5
40007 > Start register 6
40008 > Start register 7
40009 > Start register 8
40010 > Start register 9
40011 > Start register 10

The Modbus Read Request Packet for a master reading 3 registers from a slave with unit ID 100 (64 Hex) and for starting register of 40011 should be:
 

Slave ID
Function
Start Register (40011)
# of Registers
CRC Checksum
64
03
00
0A
00032C3C


To summarize, when looking at a modbus map, the starting register number to be used in the read function:

Start Register = Modbus Register 40001.

Accutech Modbus Register Mapping

Modbus RTU protocol is supported on the BR10 and BR20 Base Radios. Transmission rates of 9600, 19200, 38400, 57600, 115200 are supported with even, odd or no parity, 8 data bits and 1 or 2 stop bits. The Modbus settings are configured by using the push buttons on the base radio only. The BR10 contains 1 RS-485 port for Modbus communications. The BR20 contains 1 RJ45 connection called the "Short Haul Data" port. This port can be configured for 2-wire RS-485 or 3-wire RS-232 by a dipswich next to the serial port.

The following menu items are used to configure Modbus in the base radio via the push buttons. For a complete menu map of all Accutech Instruments, please reference the Accutech Wireless User Manual that is installed along with Accutech Manager Software an your PC.

BAUD RT - Baud Rate
DEV ID - Modbus Device ID
PARITY - Parity
STOPB - Stob bit selection
MODMAP - Register mapping options (see below)
MODADR - Modbus address of base radio
ORDER - Floating point word order

There are two user options to determine Modbus mapping in the base radio/field units. The MODMAP configuration determines if the mapping will be DEV mode (Device ID) or REG mode (Register)

Device ID Mode

  • Poll for individual devices (Base Radio and Field Units)
  • Modbus Station ID = Base Radio Modbus Station Address + Field Unit RF ID
  • Modbus starting register = 40001

Register Mode

  • Poll single Modbus station ID for complete Accutech network
  • Modbus Station ID = Base Radio Modbus Station Address
  • Field unit Modbus address are multiples of their RF ID
  • Modbus starting register = (Field Unit RF ID * 10) + 40001

Field Unit Holding Registers

Field Unit operational data is stored in a sequential block of 10 Modbus registers in the Base Radio. The Modbus Station address and the actual register addresses will vary depending on the Modbus Mapping mode set in the base radio. The Modbus Station address and register locations are described below for each Mapping mode.

Device ID Mapping Mode

When DEVMODE is selected, the base radio stores the field unit and base radio operation data (10 Modbus holding registers) in separate Modbus Station addresses. In this mode, the SCADA Host (Modbus Master) needs to send an individual poll request for each field units data and the base radio data. Station addresses are determined using Base Radio Device ID parameter and the Field Units RFID parameter. This mode is suitable for systems using a template for each field unit.

Field Unit Modbus Station Address = Base Radio Device ID + Field Unit RFID

1The default floating point format for Modbus database registers is Low Word, High Word. For example if a floating point value is in registers 40001 and 40002 then 40001 is the low word and 40002 is the high word. For SCADAPack controllers 40001 is the high word and 40002 is the low word. The floating point word order is decided by Modbus Floating Point Order of base radio Modbus Communication Configuration.

2Any field unit that is currently offline will return NaN (Not a Number) when queried for its primary, secondary or tertiary measurement value. If a field unit is online, NaN will also be returned for measurement values that do not exist in the device. For example, a field unit providing one measurement will return NaN for its secondary and tertiary values.

Register Mapping Mode

 When REGMODE is selected, the base radio stores the field unit and base radio operation data (10 Modbus holding registers) in sequential blocks of registers located at a single Modbus Station address. The base radio uses register addresses 1 through 10 with subsequent groups of 10 registers used by each field unit. Station address is determined by the base radio Device ID and the Register addresses for each field unit are offset from the base radio registers by a factor of 10 times the field unit RFID parameter. This mode is suitable for a system that wants to poll for multiple field unit devices at once.

Field Unit Modbus Station Address = Base Radio Device ID
