For a project, it would be excellent if I could control an ACOPUSmulti Power Supply module from multiple PLCs. It is planned to have multiple axes with inverter modules that are controlled individually by PLCs. All inverter modules are powered by the same ACOPUSmulti power supply. Therefore, it would be advantageous if any PLC could control the ACOPUSmulti Power Supply and also receive status information.
For one axis, there is no issue, since the power supply as well as the inverter are controlled by one PLC.
Does anybody have experience with a similar setup or have an idea where I could look up how to solve this issue?
an ACOPOS can be controlled by only PLC via EPL.
Why not just leave the PowerSupply on one PLC and control the Power-On via an OR condition and the Power-Off via an AND condition ?
PLCs should then be connected via a fieldbus or EPL- iCN.
so you could just create an array for the power supply requests, one element for each PLC. If any PLC requests the power you switch on the power supply?!
Communication could be via OPC UA. (Or like Christoph said iCN)
Thank you Christoph and Marcel for your replays and inputs. I’ll implement it the way Christoph suggeted. One Axis beeing the “main” Axis from which the power supply is controlled with the others Axis send a swich on/off signal to PLC via fieldbus.
