Programless Communications
6-1-1
Introduction
With programless communications you can read and write E5@D parameters or start and stop the
E5@D from a Programmable Controller (PLC). Communications with the PLC are performed automati-
cally by the E5@D, so there is no need to program communications.
The E5@D automatically reads
and writes PLC memory.

Features
• You can connect to an OMRON CS/CJ-series, CP-series, NJ-series, or NX1P2 PLC, to a Mitsubishi
Q-series, L-series, FX-series, or iQ-R-series PLC, or to a Keyence KV-series PLC.
• Up to 13 E5@D parameters can be assigned for reading and up to 13 E5@D parameters can be
assigned for writing in PLC memory. Each E5@D 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@D Controllers to greatly reduce setup work and setting mistakes.
You can change the PLC
memory area and addresses.
