Instrument Architecture - gefran GFX4 Configuration And Programming Manual

The modular power controller's flexibility permits replacement of previous-version instruments without changing the
control software in use.
Based on the chosen work mode (see MODBUS SERIAL COMMUNICATION), you can use the instrument in 2 different modes:
- GFX compatible mode: as if there were 4 separate instruments (recommended for retrofitting projects and/or
replacement of damaged instruments);
- GFX4 mode: as a single instrument with the same functions as 4 separate instruments, but with possibility of inter-
action among the various parameters, inputs and outputs (recommended for new projects).
New shared parameters, identified with Modbus addresses higher than 600, are accessible for both modes and permit
more advanced functions such as:
604
FLt. 2
In addition to having a CUSTOM group of parameters for dynamic addressing, GFX4 mode lets you use a single
communication network node instead of 4 nodes as in GFX compatible mode.
When programming, keep in mind that the ad-
dresses (parameters) described in this manual exist
4 times, specified by address node (ID).
