Initial Character Z or X
If there are more than one switching elements connected to an input (hardwired
OR) then the initial character Z would be used. Figure 12 shows a > MAX signal
derived from two NOCs. The serial number assigned to this signal is ZG01. If
only one switching element is connected to an input then the initial character X is
used; this is shown in Figure 11.

XH or ZH - Binary signals from a limit value monitor
The signals created in this signal area are analog values that are monitored by a
limit value monitor. The analog signals are compared with a set-point for MIN or
MAX. The resulting signals from this type of comparison circuit are defined in the
XH signal area.
Serial number assignment for the signal area XH follow the same rules as for
serial numbers in the signal area XG.
