Modbus point list

Modbus data points and structures available in RIO600 modules are described here.
Some of the addresses are reserved and unused, that is, data points always return value
"0" when they are read.
There are two alternatives for Modbus addressing. PLC addressing starts from address
1 while regular Modbus addressing starts from 0. For example, in PLC addressing a
holding register address 234 can be referred to either as 4X register 234 or as 40234.
Similarly, regular Modbus addressing at 234 can be referred to either as 4X register
233 or as 40233.
Modbus addresses in the documentation follow regular Modbus
addressing scheme with addresses starting from 0. For PLC based
addressing scheme the regular Modbus data addresses should be
incremented by one.
Modbus point list can be exported from the connectivity package.
SSR1 System status register (1) device health
System status register address provides information about the health status of the
RIO600 system and all individual modules present in its stack. It also provides status
of the UPS power failure and local/remote mode.
