How to perform C-Bus Automation Controller LUA Script logging
Hide ShowDefault Log Helper Function
The LUA Script Editor contains Helpers - under the Alerts and Logs - contains a log variables function helper which when left clicked enters an example containing some different parameters to log. The results shown in the Current logs window of running a script containing the default log helper is as follows
Logging Descriptive String and Value
Using log function can be prefixed with a string as well as the parameter(variable) to provide understanding of what it being logged. All arguments are logged to the Current logs window in example below we see argument 1 being the description and argument 2 being the variables(parameter) value.
Logging Multiple Parameters or Concatenated Strings
Using log functions containing multiple strings and/or parameters eg log('string', parameter, parameter, parameters, ....) to see descriptions and multiple variables at the specified execution point in the LUA script. Knowing what various C-Bus groups, C-Bus levels, measurement values, user defined setpoints are at a specific point in the LUA script can help determine why a block of LUA script code is or isn't being executed.
Additionally using "tostring(variable)" to convert boolean, integer, floating value's into strings and " .. " to concatenate strings allows you to condense log messages into a single line. This allows complex logic with multiple conditional statements to be checked for expected and actual execution whilst troubleshooting LUA scripting.
SwValues = 'Reed Switch: ' .. tostring(SwReed) .. ', Switch Loops: ' .. tostring(SwLoops) .. ', Switch Value: ' .. tostring(SwValue)
log('Switch Values', SwReed, SwLoops, SwValue)
returns
* string: Reed Switch: true, Switch Loops: 5, Switch Value: 83.35
How to get a C-Bus Automation Controller LUA Script IF to perform like a PASCAL Logic ONCE
Hide ShowTo avoid an if statement being executed by the C-Bus Application/Controller Event-based engine numerous times the use of an outer if (or) - then statement ensuring that the event came from visualization or from c-bus avoids the inner event-based condition being met again and again. We can use LUA script log function and the Logs window to verify expected behaviour
Without outer if (or) - then statement
Without any outer conditional check of whether the event came from either visualization or c-bus network the log windows shows that a change in state of the Group 78 (Strong Room Reed Switch) being set to ON (255) - true results in numerous executions by the event-based lua script engine which continue to occur as seen by updating timestamp.
With outer if (or) - then statement ensuring that the event came from visualization or from c-bus
With the inclusion of an outer conditional loop checking whether the event came from either visualization or c-bus network the log windows shows that a change in state of the Group 78 (Strong Room Reed Switch) being set to ON (255) - true results in one execution and that another change in state of the Group 78 (Strong Room Reed Switch) being set to OFF (0) - false results in one execution. From the Logs window we can see that the added if (or) - then ensuring that the event came from visualization or from c-bus acts similar to a ONCE statement in PICED pascal logic
How to troubleshoot C-Bus Automation Controller LUA Scripts
Hide ShowSave Script - Syntax errors are shown when saving the script
These errors relate to general LUA command/statement syntax
example 1: in following if - then - else - end condition the following LUA script is missing the closing "end" statement
if (StrRmReedSwitch == false) then
-- Turn ON the Store Room Alarm and Alarm Light

results in the following error when attempting to save
Show Error Logs - Logical errors are shown when "Error log" is selected (1), and from the Error log window selecting "Show errors only for current script" (2) and "Clear" (3) then running the LUA script - by changing related object statuses etc in Object Tab, Visualization or Run Script
Logic errors relate to logical issues with the LUA Script such as trying to retrieve the state of an uninitialized group or trying to retrieve the state of a group that does not exist, or performing incompatible arithmetic etc.
example 2: Library cbuslogic:0: unable to find 0/56/250 --- (check if application 56, group address 250 object exists?)
example 3: Library cbuslogic:0: unable to decode 0/56/150 --- (check if application 56, group address 150 object currently nil "un-initialized")
example 4: User script:5: attempt to perform arithmetic on global 'StmRmTempSwitch' (a nil value) stack traceback: --- (check compatibility of arithmetic)
The following LUA script tries to perform a mathematical addition of a boolean returned from GetCBusState and an integer value resulting in Error log message
-- Get state of Store Room - Reed Switch on the local network
StmRmTempSwitch = GetCBusState(0, 56, 78)
IntValue = 5
CalcValue = IntValue + StmRmTempSwtich
Log messages which can help further troubleshoot LUA script issues are shown when "Log" is selected (1), and from the Current logs window selecting "Show logs only for current script" (2) and "Clear" (3) then running the LUA script - by changing related object statuses etc in Object Tab, Visualization or Run Script
Log messages can be used to log values of c-bus states, levels, variables and determine whether expected conditional and behavior is being met or may provide answer why a condition is not met and a certain block of the LUA script is not being executed.
example 5: Running the following script shown in image and turning the Strong Room Reed Switch group OFF and ON shows script is working as expected.
