is completed.
When the complete device + 1 (abnormal completion signal) turns ON, the error

When the C24 I/O signals are from X/Y00 to X/Y1F:
1) Specify the receive channel.
2) Clear the reception result and receive data count storage device to 0.
3) Specify the allowable receive data count.
4) Store the receive data in the specified device.
5) After completed, the receive data within the allowable receive data count (user-
specified) is read from the receive data storage area in the buffer memory.
Once the INPUT instruction is executed, the read completion signal (M0) specified
by user turns ON for one scan.
6) The receive data of the receive data count is transferred to D110.
7) The abnormal completion flag is reset by an external command.
