Network Instructions
Section 3-25
In this case, the Number of Contact Operations is being set to 500 (1F4 hex),
so the service data is set to 000001F4.
3-25-9 EXPLICIT WORD READ: ECHRD(723)
Purpose
Reads data to the local CPU Unit from 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.
