Appendix 2 Comparison of the Q64TCN with the Q64TCTT, Q64TCTTBW, Q64TCRT, and
Q64TCRTBW
Appendix 2 Comparison of the Q64TCN with the
Q64TCTT, Q64TCTTBW, Q64TCRT, and
Q64TCRTBW
The Q64TCN has several new functions in addition to the functions of the Q64TCTT, Q64TCTTBW, Q64TCRT, and
Q64TCRTBW (hereafter abbreviated as the Q64TC).
This section describes the comparison of functions, I/O signals, and buffer memory between the Q64TCN and Q64TC
in accordance with the addition of the new functions. Precautions on replacing modules are also explained.
(1) Comparison of the functions between the Q64TCN and the Q64TC
The following table lists the functions supported by the Q64TCN and the Q64TC.

Alert function
The reference set value (SV) for the deviation alert can be selected from
among the following buffer memory areas with the Q64TCN. ( Page
194, Section 4.12)
•CH Set value (SV) monitor (Un\G25 to Un\G28)

RFB limiter function
Sensor correction function
Errors can be corrected by setting any two points (corrected offset value
and corrected gain value) with the Q64TCN. ( Page 213, Section
