Lc 241/Lc 242 Io Terminal Mapping, Modular Version - Grundfos CIM 200 Functional Profile And User Manual

9.10 LC 241/LC 242 IO terminal mapping, modular
version
LC 241/LC 242 consists of a control cabinet with a CU 241/CU
242 control unit, an IO 242 pump module for connection of one or
two pumps, some basic IO signals and an optional IO 241 module
for extra IO signals. The mapping of the wire terminals to Modbus
registers for the two IO modules are shown in this section.
