Network Instructions
Section 3-25
When CIO 000000 and A20206 (the Communications Port Enabled Flag for
port 06) are ON, ECHRD(723) reads D00000 to D00002 from the I/O memory
of the CJ-series CPU Unit with node address 07 on the DeviceNet Network
and stores the data in D00100 to D00102 of the local CPU Unit.
3-25-10 EXPLICIT WORD WRITE: ECHWR(724)
Purpose
Writes data from the local CPU Unit to another CPU Unit in the network. (The
remote CPU Unit must support explicit messages.)
This instruction is supported only by CS/CJ-series CPU Unit Ver. 2.0 or later.
