Head device No.
* 1 : Only multiples of 16 can be set for both the head device No. and the number of transferred bits.
* 2 : Since the QA base (QA1S6 B) cannot be connected, the A/QnA series intelligent function
modules are not the target.
(When the QA base (QA1S6 B) is connected, "PARAMETER ERROR (3006)" is detected.)
"PARAMETER ERROR (3006)" is also detected if an error occurs in intelligent function module
mounting check or buffer memory capacity check.
* 3 : Only when the specified number of transferred words is 1, an odd address can be specified.
POINT
It is recommended to mount the target modules of this function on the main base
unit.
(Access time to modules mounting on the main base unit is shorter than that on
the extension base unit.)
