PI Interfaces for Modbus

Showing 8 of 4920

Modify the Modbus Interface to accept 32-bit Unsigned Ints from the PLC

Support multiple Modbus devices on the same machine

Add support for multiple Modbus devices (using the same IP address but different port numbers) on the same machine. For example, the interface could allow the user to configure something like this: /dn= xxx.xx.xxx.xx:43120,/cn=1,/polldelay=0,/to...

Add Mod10 to Custom Data Type Manipulator for Modbus Interface

Please add support for SquareD Mod10 custom datatype to the Modbus Interface. Schneider Electric uses a custom datatype that uses four 16 bit registers. Each register represents an integer. Each integer is then multiplied by a factor and all resu...
