Modbus/TCP Protocol
CIE-M10 supports Read Multiple Registers (Function Code: 3) and Write Multiple Registers
(Function Code: 16) among the Modbus/TCP‟s function codes. Read Multiple Registers is for
reading the CIE-M10‟s input port value and Write Multiple Registers is for writing the CIE-M10‟s
output ports.
Because CIE-M10 supports both Master and Slave mode and both active and passive TCP
connection, it can adapted in various environments.
