20.6 Receiving Data Using the Bidirectional Protocol
■
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.
■
Control data
*1 The amount of the data to be received must be set in units as specified in the engineering tool. For byte specification, set the number of
bytes. For word specification, set the number of words.
Processing details
• The data received using the bidirectional protocol of the module specified by (U) is stored in the device specified by (d1)
and later, according to the control data in the device specified by (s) and later.
• The completion status of the G(P).BIDIN instruction can be checked with the completion device (d2) and the completion
status indication device (d)+1.
• The following figure shows how the G(P).BIDIN instruction operates when completing its execution.
