* 1 : Only multiples of 16 can be set for both the head device No. and the number of transferred bits.
* 2 : Since the AnS/A series-compatible extension base unit (QA1S6 B, QA6 B) cannot be
connected, the AnS/A series-compatible special function modules are not included. (A
"PARAMETER ERROR" (error code: 3006) occurs when the AnS/A series-compatible extension
base unit (QA1S6 B, QA6 B) is connected.)
A "PARAMETER ERROR" (error code: 3006) also occurs when an error is detected in the
intelligent function module mounting status check or buffer memory capacity check.
* 3 : Only when the specified number of transferred words is 1, an odd address can be specified.
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.)
