Query
Response
*1. Broadcasting cannot be performed.
*2. Note that the coil start number is 0004, which is 1 less than the coil number 0005.
*3. If the number of coils to be read is set to 0 or more than 32, an error code (03 hex) will be returned.
*4. Data as much as the number of data bytes will be transferred.
Data received to a response shows status of coil No. 0007h to 000Eh (Input terminal 1 to 8).
Therefore, the received data “17 hex = 00010111 binary” can be read from the LSB that shows the sta-
tus of coil number 0007 hex, as follows:
If, in the last coil data, the read coil exceeds the defined coil range, such out-of-range coil data will be
transferred as 0.
If the Read Coil Status function is not executed normally, refer to
No.
