Either ‘Enabled’ or ‘Disabled’. When there is a partner module acting
as a standby unit this option should be set to ‘Enabled’ to allow
exchange of data between the two modules.
These five drop-down boxes can each be set to ‘Enable’ or ‘Disable’
the related Emergency Shut Down signal, depending on the particular
site requirements. In general the settings should be ‘Disabled’ unless
the particular Emergency Shut Down function is required. The action for
each individual actuator has to be set locally on the actuator to either
close, open or stay put (no movement on receipt of the ESD signal), as
required for each valve; refer to individual actuator manuals.
These five drop-down boxes can each be set to ‘Enable’ or ‘Disable’
the host system commands to the actuators and field units from the
indicated source of the signal. For example, commands over the
Ethernet connection can be disabled, whilst those from Serial Port 1
can be enabled. Ethernet commands are those sent via the Ethernet
ports from the host system using Modbus TCP. Commands on the
individual field unit web pages can also be disabled. Serial Port 1 and
Serial Port 2 are the RS-232/RS-485 Modbus RTU ports, which are
commonly used for control and monitoring. The Keypad is the control
source on the front panel of the CPU module.
These four drop-down boxes can each be set to ‘Enable’ or ‘Disable’
the copying of information between the A side and B side CPU and
Option modules in a hot standby system. They do not appear in a
single module system.
Settings - Enable to copy all the settings, except those listed below,
between the units.
Address - Enable to copy the Modbus addresses of the CPU (P3
option) and Pakscan Loop option module between the
units.
Tag - Enable to copy the Site name and system Tag name
between the units.
IP - Enable to copy the IP address and Ethernet settings
between the units
This drop-down box contains the options enabling the system language
to be chosen. The options are English, Spanish (Espanol),
French (Francais), German (Deutsch), Italian (Italiano) and Hungarian.
A text box is provided in which the system PIN can be entered, and a
drop-down box provides the options for access permission when using
the CPU keypad and screen.
Note that the ‘Command Settings’ above can be used to prevent
keypad commands under all circumstances, but when the keypad is
enabled the security settings below will apply.
PIN - The Password number is a variable between 0 and 9999. When
a number is entered, it indicates that the PIN must be used for
settings or commands to be allowed from the CPU keypad in
accordance with the associated drop-down box setting.
