Appendix 11 Outputting any characters from a decoded character string
On a programmable controller side
When specifying an output range of a character string on a programmable controller side, the range can be specified by
creating a program using the MIDR instruction.
The specifications and operation examples when using the MIDR instruction in MELSEC iQ-R series CPU modules are
shown bellow.
For details on the MIDR instruction, check in the manual of the CPU module used.
Extracting the specified string data MIDR(P)
These instructions extract data at any position in string data, and store the extracted data in the device number specified by
(d) and later.
