 Fault page data. These variables will help you create your own FAULT page in your HMI just the way
they appear in your GENSYS 2.0 module. This way you don’t have to scan all faults/protections
handled by your CRE Technology module.
Note: Data available concerns only faults that appeared after the last power up sequence. Events appeared
before GENSYS 2.0 was switched OFF and ON again will be listed in the FAULT pages but not inside those
variables.
Table below lists those two kinds of variables.

2/ Sharing digital input and Modbus control over a single function
If you need to control a specific function (for example REMOTE START E2514) both using Modbus and logic
inputs, please follow instructions as described in the example below to avoid conflicts between logic inputs
and Modbus write accesses. In this example, remote start E2514 is controlled both by input J8 and through
Modbus access. This means that both can start the generating set. To do so, a virtual input (here Virtual
input 1 E2283) is setup the same way as input J8 and is then controlled through Modbus.
 Set parameter E1269 “DIJ8 function” to 2514.
 Set parameter E1328 “VI01 function” to 2514.
 Write 1 or 0 into E2283 (“Virtual in 01”) using Modbus to set virtual input to the desired value.
 This way, both physical input J8 and virtual input 1 are considered as inputs controlling variable
E2514.
Variables
Description
E2640…E2649
Bitfields variables. Each variable contains the current value of 16 logic variables such as
circuit breaker positions, faults, alarms…
Refer to document Z0 90030_.xls to get the complete list of variables packed inside
bitfields.
E0516…E0535
Fault 1 to 20. A negative value indicated that the fault is ON. A positive value indicates
that the fault is OFF. A zero means “no data”.
E0516 is the most recent event listed.
Example :
E0516 = -2005 means that emergency stop is active (E2005 = emergency stop).
E0516 = 2005 means that emergency stop has been released.
E0821…E0850
Fault 1 to 20. A negative value indicated that the fault is ON. A positive value indicates
that the fault is OFF. A zero means “no data”.
E0850 is the most ancient event listed.
Example :
E0842 = -2005 means that emergency stop is active (E2005 = emergency stop).
E0842 = 2005 means that emergency stop has been released.
