20.4 Receiving Data Using the Nonprocedural Protocol
G.INPUT
This instruction receives data in a user-defined message format by using the nonprocedural protocol.
■Execution condition
■Description, range, data type
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
■Applicable devices
*1 Index modification is not available.
*2 FX and FY cannot be used.
*3 RD cannot be used.
*4 FD cannot be used.
*5 T, ST, C, and FD cannot be used.
