20 SERIAL COMMUNICATION INSTRUCTIONS
20.8 Receiving Data Using an Interrupt Program
Precautions
• When data is to be received with the interrupt program, use the Z.BUFRCVS instruction.
• The following table summarizes the processes that take place if another instruction is issued while the Z.BUFRCVS
instruction is active or the Z.BUFRCVS instruction is issued while another instruction is active with the same channel.
*2 The following instructions are not available with the same channel as for the Z.BUFRCVS instruction because they use a communication
protocol different from the one used by this instruction.
• For the receive data storage device for the Z.BUFRCVS instruction, secure in advance the area larger than the amount of
data that will be received from the external device. If it has not been secured, the data located at the rear of the storage
device will be overwritten.
• The local device and the file register for each program are not available for setting data.
• The read error codes issued during occurrence of a receive error can be read from the data receive result storage area
(address: 258H/268H) of the buffer memory.
Operation error
Instruction to execute
concurrently
Possibility of
concurrent execution
Handling for concurrent execution
G(P).OUTPUT
G(P).PRR
G.INPUT
The G.INPUT and Z.BUFRCVS instructions cannot be used simultaneously.
Concurrent execution is, however, possible if they use different channels.
G(P).BIDOUT
G(P).BIDIN
Concurrent execution of the G(P).BIDIN and Z.BUFRCVS instructions is not possible.
Concurrent execution is, however, possible if they use different channels.
ZP.CSET
G(P).PUTE
G(P).GETE
Z.BUFRCVS
G(P).SPBUSY
ZP.UINI
• G(P).ONDEMAND and G(P).CPRTCL instructions
