[CON] Analog Constant
Function
CON
Outputs a user defined analog constant. This value can be changed via: the PCC-IV Editor menus
(under password protection), via USB Blockware download, or via the MODBUS communications link (using
PLINK
F124). This value cannot be changed from the PCC-IV front panel Operator displays during normal operation.

[FPCON] Front Panel Adjustable Constant
Function
FPCON
outputs a user defined analog constant. This value can be changed via: the PCC-IV front panel
Operator displays during normal operation, or via the Modbus communications link. This value cannot be changed
from the PCC-IV Editor menus, nor via the USB Blockware download. This function is used for Operator adjustable
setpoints, ratios, channel select
ions, etc. …
A
FPCON
Block must have a Tag associated with a Display Channel in the Panel Data Screen to allow the Operator
to be able to change the value from the front panel Operator displays. The MIN and MAX parameters limit the range
of adjustment that can be made.
At power down, the Block Output is saved in the Retentive Memory area of the NVRAM. During the first scan after
CPU start-up, the
FPCON
Block Output is set to the value stored in the Retentive Memory.
