Good Morning Marinus, I trust you are well. We are testing a new setup for our wallet system using the Eastron meters with built in contactors. So I loaded it as a generic modbus meter but then PnP doesn't allow us to add a contactor. Please can you advise. Thanks.

Can you control the contactor via a Generic Modbus coil?
sdg.marinusvz 2024-08-22 10:40
The supplier said we should be able to switch it on & off via PnP
sdg.marinusvz 2024-08-22 10:40
think you misunderstand my question
You can add an entity on pnpscada called a 'Generic Modbus coil'. Give it the modbus address and the coil address to switch. Then tie your contactor to that entity to switch the meter
sdg.marinusvz 2024-08-22 10:40
Marinus forgive my ignorance, but I don't see that option. Only Generic Modbus Meter
Generic Register Meter
Generic STS Meter
sdg.marinusvz 2024-08-22 10:40
it is under RTUs, I think: add->RTUs->Generic Modbus Coil
sdg.marinusvz 2024-08-22 10:41
Okay I see. So I must remove the meters and add it as a Generic Modbus Coil?
sdg.marinusvz 2024-08-22 10:41
no. Leave the meters as is
sdg.marinusvz 2024-08-22 10:41
Can the Modbus and coil address be the same?
sdg.marinusvz 2024-08-22 10:42
yes (modbus address can be the same). They share the same communications device, right?
so requests should be serialized
The corresponding modbus meter should not use coils or coil addresses

update: the Generic Modbus Coil is now called the Generic Modbus Digital output, since the entity now support more kinds of modbus registers than just Coils. It depends on the particular Modbus device.
