12 NETWORK COMMON INSTRUCTION
12.1 Link Dedicated Instructions
• When a number from 1 to 120 is specified for the target station number, the instruction should be executed
with the execution type set to "Arrival acknowledgment used" to improve data reliability. When a group
number or all stations are specified, the instruction should be executed with the execution type set to "No
arrival acknowledgment".
• When sending data to the same channel in the receiving station, execute the instruction after data has been
read by the GP.RECV instruction in the receiving station. When the execution type is set to "No arrival
acknowledgment", successful completion results in the sending station if communication is completed
successfully even when the sending data contains an error. Also, even when the sending data is normal, a
timeout results in the sending station if the instructions are executed for the same station from multiple
stations.
• With the execution type set to "Arrival acknowledgment used", if the sending station sends data to the same
channel in the receiving station before the receiving station reads data using the GP.RECV instruction, a
buffer full error results in the sending station.
• When multiple network modules are mounted in the target station, specify the network number and station
number of the network module that receives a request from the own station.
(Example: In the following figure, specify station No. 1 of network No. 1. (Station No. 5 of network No. 2.
cannot be specified.))
• The number of resends (s1)+7 must be set every time the instruction is executed.
