The completed position number and zone signal
status are output. Read the completed position
number as a six-bit binary value.
If an alarm is present (= the ALM signal is ON), a
description of the alarm is output as the
completed position number.
(For the alarm descriptions to be output, refer to
the next table, “Alarm Description List.”

*1 The maximum number of positioning points is 16 under PIO control with ERC2-NP/PN controllers.
When the Gateway Unit is connected, however, up to 64 points can be specified.
*2 [ZONE 2] cannot be used with ERC2-NP/PN controllers.
