Security - The drop-down box contains the options for selecting the
protection afforded against inappropriate actions when using the
CPU keypad.
None : All settings and control commands accessible via the
keypad without protection by a PIN.
Set up : Control commands accessible via the keypad without a
PIN, but all setting changes via the keypad require the PIN to be
entered first.
Set up and Control : Any control command action or setting
changes via the keypad require the PIN to be entered.
Locked : No keypad access permitted for any control commands
or setting changes whilst there is host activity on any of the serial
or Ethernet data links. [If all serial and Ethernet communication
links are inactive for 5 seconds then keypad commands can be
entered provided the PIN is entered (as with the Set up and
Control level)].
The version of software fitted to the CPU module. In hot standby
systems the modules in both the A and B side should have the same
version of software.
This setting relates to the wireless option only. Whilst the frequency
band over which the wireless communicates is a globally available
band, there are frequencies within this band that certain countries do
not allow. This parameter is set up during the first 5 times that the
master station is powered up or by using the HMI menu A3F. This
setting will ensure that that the channels made available for selection
within the wireless option module are only those legally available within
that particular country.
This value is derived from the actual hardware of the CPU and
indicates the maximum number of actuators or field units that can be
connected to this system. The field units can be split between the
option modules fitted.

Using the slider bar the user is able to select the number of field units
connected to each option module fitted in batches of 60. Simply select
and drag the bar to the appropriate setting with the mouse, the text
above the bar will indicate what has been selected.
The bar will only allow selection up to the maximum number of field
units available on the master station in question.
This bar only selects the number of field units allocated to the two
option slots and not the address range of the field units on the option
slot network. The Pakscan 2 loop actuators will always start at address
1. In the example shown on the next page, where there are 180
devices on the Pakscan 2 loop module, the addresses 1 to 180 will be
for the Pakscan 2 loop units. The starting address for the wireless
devices is set up in the wireless configuration section and this would
logically (but not necessarily) be set to 181. This would mean that the
addresses for the 60 wireless devices can range between 181 and 240.
