We use Foxboro IA system v8.8 DCS.
The blocks that i have problem controls proportional valves.
When we turn the PIDX block to manual, we set an output value and it must stay at that value. But in manual, the output value changes slowly.
I checked the block but couldn't see anything...
We have been use ACS800 drives for a long time over Profibus by its RPBA-01 module.
ACS800 drives will not produced anymore. So, we began to use ABB ACS880 drives. ACS880 uses FPBA-01 adapter module for profibus.
I try to communicate ABB ACS880 drive with DCS using RPBA-01...
I try to control ABB MNS Mlink (It controls M10x modules) motor control module with AB ControlLogix 1756-L71 and Prosoft MVI56E-MCM combination. I send start and stop commands, toggle related start stop bits on ControlLogix program but, Mlink reacts too late or many times does not react.
We use 2878696 IL MOD BK DI8 DO4-PAC modbus copuler with these components at this order:<pre>
1- 2878696 IL MOD BK DI8 DO4-PAC
2- 2878447 IB IL AI 4/EF-PAC
3- 2861302 IB IL AI 2/SF-PAC
4- 2861302 IB IL AI 2/SF-PAC
5- 2861315 IB IL AO 1/SF-PAC
6- 2861315 IB IL AO...
I made the Controllogix program and set up the MVI module as Modbus. I wired an energy analyzer and made all communication parameters such as address, baudrate, etc. But no communication.
At my program under MCM.config, there is a configuration list for port1. I made it true.
we read accumulated active energy and reactive energy with 2700 and 2708 registers. At the beginning of the ever month, we want to reset these accumulated values in the analyzer.
What is the way of doing this?
I couldn't find the related register for this, in its register list...
