(7)PC link protocol transmission (Data read)

The T series PC link protocol allows a T2N or T3H on a network to read register data from another T2N’s or T3H’s registers into its own registers.

∙Register read request (using the RECV instruction)

(a) Function

The register data designated by the remote station (T2N/T3H) is read to the designated register on the local station (T2N/T3H).

(b) Transfer parameters
