Sending Commands From a PC Section 5-3
Note With CS/CJ-series PCs, the Communications Port Enabled Flags at bits 0 to 7
in word A202 turn OFF even when the PCMR(260) instruction is being exe-
cuted using the ports corresponding to those flags.
5-3-3 Transmission Delays
The methods of computing the maximum time required from execution of the
SEND(090), RECV(098), and CMND(490) instructions until processing is
completed are described in this section. These times, however, do not take
transmission delay times on the network into account, so they may be
increased depending on the conditions under which the instructions are exe-
cuted.
When the Communications Port Enabled Flag for port 7
is ON, and SEND(090) is not being executed, the trans-
mission execution program will start when execution
condition CIO 000001 turns ON.
Input CIO 120002 remains ON from the start of
RECV(098) execution until completion.
