Insert the ERM Module
The DL205 system only supports the placement of the ERM module in the CPU base. It
does not support installation of the ERM module in either local expansion or remote I/O
bases. The number of useable slots depends on how many slots the base has. All of the DL205
CPUs support the ERM module, except the D2-230.
NOTE: The module will not work in slot 0 of the DL205 series PLCs, the slot next to the CPU.
Network Cabling
Of the three types of ERM modules available, one supports the 10BaseT standard, another
supports 10/100BaseT and the other one supports the 10BaseFL standard. The 10/100BaseT
standard uses twisted pairs of copper wire conductors and the 10BaseFL standard is used with
fiber optic cabling.
