USER MANUAL – Z-TWS4/Z-PASS2-S/S6001-RTU
45
It should be noted that two “DIx” variables and four “DOx” variables are declared, corresponding to the
maximum number of inputs and outputs possibly available; the Digital I/O configuration (see paragraph
18.1.13) determines which of these variables are actually handled by the PLC; for example, if DIDO1 is set
as an input and DIDO2 as an output, DI3 and DO4 will be handled while DI4 and DO3 will not be used.
Moreover, while the variables corresponding to the inputs are updated by the PLC regardless of their
function modes, only the variables corresponding to the outputs set as “General Output” will actually affect
the digital outputs.
8.2 Energy Management Protocols
The StratON soft-PLC installed on Z-TWS4/Z-PASS2-S/S6001-RTU supports the following “Energy
Management” protocols:

IEC 60870-5-101 (Master/Slave)

IEC 60870-5-104 (Master/Slave)

IEC 61850 (Master/Slave)
The activation of these protocols is license-based.
Please contact Seneca to get more information about getting the license for Energy Management protocols.
8.3 StratON Redundancy
WARNING!
At the date of this manual, the “StratON Redundancy” functionality is still in a “Beta version”; this means
that the proper operation of this functionality is not guaranteed for every kind of application; please contact
Seneca for further information.
The StratON PLC provides a “Redundancy” functionality:
when this feature is enabled, two CPUs (Z-TWS4 or Z-PASS2-S or S6001-RTU) run the same StratON
application; the two CPUs connect each other via the Ethernet, in order to keep variables, state-machines
etc. synchronized between them; in each moment, only one of the two CPUs actually runs the application
and drives the fieldbus; if, for any reason, that CPU stops running, the application execution is handed over
to the second CPU.
