9.10 JP/GP.RECV (Data Reception from Programmable Controllers on Other Stations)
(d) RECV instruction execution timing
When data are stored in the own station channel area, the corresponding RECV execution request flag
(SB0030 to SB0037) turns ON.
Use a RECV execution request flag as a start contact to execute the RECV instruction.
Upon completion of the RECV instruction, the RECV execution request flag turns OFF.
• When completed normally
For the RECV instruction execution timing, refer to the following.
Page 407, Section 9.9 (3) (e)
• When failed
(4) Error
When a link dedicated instruction failed, the error details can be confirmed by either of the following methods.
(a) With the programming tool
The error details can be checked in the CC IE Control diagnostics. ( Page 526, Section 10.3)
(b) Checking devices
Completion status indication device ((D2)+1) is turned ON, and an error code is stored in Completion status
((S1+1) of control data.
Check the error and take corrective actions according to the error code. ( Page 511, Section 10.2)
