33.4 FNC293 – LOGR / Logging R and ER
Outline
This instruction logs specified devices, and stores the logged data to extension registers (R) in the RAM and extension
file registers (ER) in a memory cassette.
1. Instruction format
2. Set data
*1. C200 to C255 cannot be set.
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (LOGR and LOGRP)
While the instruction is driven, “m” devices starting from are logged until “n” sectors of extension registers (R)
starting from and extension file registers (ER) in a memory cassette are filled.
The number of logged data is stored to .
If a memory cassette is not used, data is not written to extension file registers (ER).
