20.7 Reading the Data Send/Receive Status
1695
20
Processing details
• The execution status of the instruction to the module specified by the start I/O number is read and stored in the device
specified by (d) and later.
• In the associated bit of the device specified by (d), "1" is stored when each instruction starts its processing, and "0" is stored
when the instruction completes its processing. Completion of processing of each instruction is at the time when the
completion flag of the instruction changes from on to off.
• If the instruction has been set to be executed while being on, the G(P).SPBUSY instruction operates every scan while the
read instruction is on; if the instruction has been set to be executed at the rise, it operates only one scan when the read
instruction rises from off to on.
• While the G(P).SPBUSY instruction is active, another instruction can be executed. In addition, while another instruction is
active, the G(P).SPBUSY instruction can be executed.
Operation error
(1) Execution status of the G(P).ONDEMAND, G(P).OUTPUT, G(P).PRR, or G(P).BIDOUT instruction for channel 1
(2) Execution status of the G.INPUT or G(P).BIDIN instruction for channel 1
(3) Execution status of the G(P).ONDEMAND, G(P).OUTPUT, G(P).PRR, or G(P).BIDOUT instruction for channel 2
(4) Execution status of the G.INPUT or G(P).BIDIN instruction for channel 2
(5) Execution status of the G(P).GETE or G(P).PUTE instruction
(6) Execution status of the G(P).CPRTCL instruction for channel 1
(7) Execution status of the G(P).CPRTCL instruction for channel 2
