      What modules support the 140 XSM00200 16 point discrete simulator module connector?

      The simulator module connector is designed to operate with the 140DAI 540 00 and the 140 DAI 740 00 modules. These modules are 115 and 230 volts AC and field wire in the same manner. If the power source was reduced to 30volts or less AC the module 140DAI 353 00 could also be used for simulating discrete inputs.

      Changing counter value while Hot Standby switchover

      Goals and Symptoms

      This resolution describes a workaround for an effect by a Hot Standby switchover with RIO and a software counter.
      The RIO cable connection to the Primary CRP 931 fails.
      An input from a 140 DDI 353 00 module has value "1" at the same time.
      The Standby system switches to Primary (what is correct).
      But the input bit gets for a short time the value "0", because the CRA is not available while switchover.

      If the binary input is linked to a software counter the counter will change the value. Also affected are program parts, which use this binary input together with Edge detection.

      Facts and Changes

      Problem is known with the following components:
      Concept 2.6 SR2
      140CPU43412A, EXEC 1.25, Kernel 1.01
      140CHS11000, EXEC 1.04, Kernel 1.00
      140CRP93100, EXEC 1.15, Kernel 1.01
      140 DDI 353 00

      It should exist with all Hot Standby systems equiped with 140CRP93100, every discrete Input and a software counter or a Edge detection is linked to the Input module.

      Causes and Fixes

      Use the EN input of the software counter and link it to the healthy bit of the Input module. This avoids to increase the counter during RIO cable interrupt.
