FNC293 – LOGR / Logging R and ER
Outline
This instruction logs specified devices, and stores the logged data to extension registers in the RAM and
extension file registers 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).
