Dear forum. We are commissioning soon, a machine which will work remotely most of the time (not plugged to the mains during normal operation). In order to achieve this, we are using the QUINT4-UPS/24DC/24DC from Phoenix Contact (part number: 2907070) with Ethercat extension. The PLC and I/O we are using are from Beckhoff. We want to accomplish the following requirements:

1)  Display the status of the UPS in the PLC screen (buffer time, state of charge etc).

2) When the machine is not connected to the mains, initiate the machine from the battery (cold restart) through a switch (switch in ON position). According to the UPS manual in the Phoenix contact website, we have to connect (3.8) bat. start with (3.9) SGND through a NO contact of the switch for example.

3) When the machine is not connected, switch off the UPS when switch is in OFF position, through a NC contact of the switch. According to the UPS manual this should be possible when connecting (3.6) remote to SGND (3.9) through a NC contact. However, when the machine is plugged into the mains and switch is OFF ((3.6) connected to (3.9)), we want the UPS to remain ON and charge the battery since it is connected to the mains, but deactivate the buffered outputs. 

In order to achieve these requirements, from what I have understood, we have to configure the 32 bits of the SET PARAMETER value shown in the attached, found in the manual. The default value is 0x01901020 and has to be changed to 0x01901820, to deactivate the buffered outputs. 

The problem I experiencing is that I can not set this parameter in Twincat (the development program for Beckhoff PLCs). When I change the online value to 0x01901820, the result is 0x018000110. I do not know how to change the SET PARAMETER value in Twincat, and I am not sure if the SET PARAMETER configuration is correct. Any advice/help would be highly appreciated, thank you in advance for your kind consideration.
