Appendix
*8 The control data alarm statuses of registers D7614 and D7615 indicate the statuses of alarm numbers 1
to 4 of each loop using the bit status of the register (16 bits).If the status of alarm numbers 1 to 4 of each
loop is ON, the corresponding bit is set to 1 regardless of the alarm type. When the data is read using
ladder communications, the 16-bit signed data converted to BCD is returned. Therefore, the host
computer must convert the value to 16-bit signed integer. If registers D7614 and D7615 are read on a 0-
loop model or if register D7615 is read on a two-loop model or four-loop model (or when four loops are
selected in the “Basic setting” on a six-loop model), “0” is returned.

Note
• If data of a register related to an uninstalled loop is read, a “0” is returned.
• If the data of a register assigned to auto/manual/cascade switching, run/stop switching, or
remote/local switching is read immediately after the CX powers up or immediately after
reverting from the basic setting mode, “D1” may be returned.
