Hi,

I am facing problem related to Coils(0x) in Concept + Citect based project. System is already working. My job here is to modify logic/scada to include some new equipments. While simulating logic at office, we did few observations, which are as follows:

<b>1) Can't change/write to coil(0x) values through 32-bit simulator or HMI.</b>

2) Where as Holding Register (4x) values can be changed/written through HMI/Simulator

3) 0x Coil values can be changed only in reference table after Disabling particular address/variable

4) 0x, 1x, 3x, 4x can be read in SCADA

5) In 32-bit Simulator, coils are shown gray and not Red or Green

6) Simulator is connected through IEC 32-bit simulator option

7) HMI is connected to PLC through Inbuilt MODNET Protocol

8) After removing Disable option for 0x variable, value immediately changes to 0 in RDE Template.

Please help to find a problem.

Thanks.

 

With few more trials, I guess, it is problem with concept 32-bit IEC simulator.

If anybody knows about this, then pls reply.
