Schneider RMH modbus - PassivPluss - 11.04.2017
Hi
I am triyng to make a Modbus profile for Schneider RMH.
Here is an modbus manual parameters that read different toroids and gives status of alarm og prealarm and so on.
How can this be made into a profile?
I have many other Modbus slaves and earlier we've been instructed not to mix both scripting modbus and profile modbus so therefore a profile is best.
The profile is to be loaded on Spacelynk

You should use value_bitmask field to get each bit from a register separately: 0x01 will give you the first bit, then 0x02, 0x04, 0x08, 0x10 and so on.
RE: Schneider RMH modbus - PassivPluss - 11.04.2017
Ok. So then i use 12 different lines for the 12 toroids. Like my example underneath
{"bus_datatype":9,"bus_address":27654,"address":200,"Value_bitmask":0x01,"value_nan":[65472,0],"type":"register","units":"","name":"Channel 1","datatype":"int32"},
{"bus_datatype":9,"bus_address":27655,"address":200,"Value_bitmask":0x02,"value_nan":[65472,0],"type":"register","units":"","name":"Channel 2","datatype":"int32"},
{"bus_datatype":9,"bus_address":27656,"address":200,"Value_bitmask":0x04,"value_nan":[65472,0],"type":"register","units":"","name":"Channel 3","datatype":"int32"},
RE: Schneider RMH modbus - admin - 11.04.2017
First, make sure that all properties are in lower case or it will not work (you have Value_bitmask).
Correct address for Alarm status is 201 (202 - 1 = 0xC9), there's no NaN value there. It's a single register, so datatype is not needed, bus datatype must be Boolean.
{"bus_datatype":"bool","bus_address":27654,"address":201,"value_bitmask":0x01,"type":"register","name":"Channel 1"}

Hi,
Would it be possible to ask for the modbus template for this RMH device?
Best regards
