Application note

Digital Input Channel description

Input channels provided by PROCES-DATA contain much more than just the basic input function. The input channel functions and associated parameters are formed into a channel description. The module’s integrated controller handles all channel functions.
Functions need only to be configured for operation – no additional programming is needed.

Maintenance log

Each input channel contains an area for entering information about the last maintenance activity on the particular channel or the device connected.
Date and Time, plus a code for the applied maintenance, can be entered.
(See also: Maintenance.)

Module parameters

All parameters in the module can be adjusted at installation time using VIGO, or they can be set-up by programmed controllers. Any data described as preset values in this document, can be changed at any time by external controllers to utilise the dynamic behaviour of the intelligent functions within the module.
Parameters and data are stored in FLASH memory and are thus retained if power is removed from the module.
