6-1 Programless Communications
With programless communications you can read and write E5
@
C parameters or start and stop the
E5
@
C from a Programmable Controller (PLC). Communications with the PLC are performed automati-
cally by the E5
@
C, so there is no need to program communications.
• You can connect to an OMRON CS/CJ-series or CP-series PLC, to a Mitsubishi Q-series, L-series,
or FX-series PLC, or to a Keyence KV-series PLC.
• Up to 13 E5
@
C parameters can be assigned for reading and up to 13 E5
@
C parameters can be
assigned for writing in PLC memory. Each E5
@
C Controller is allocated 30 words of PLC memory.
(Only 12 parameters can be read for Mitsubishi FX-series or Keyence KV-series PLCs.)
• You can set the PLC memory area and addresses to use for programless communications.
• You can copy settings between E5
@
C Controllers to greatly reduce setup work and setting mistakes.
