Communication Hightec HMI and Bosch Rexroth L20 PLC

Dear Sirs,

in my current application, I am using a Bosch Rexroth L20 PLC communicating with Hightec PWS-6A00T-N HMI, but in the configuration of ADP6.5.0 software (Hightec HMI), I cannot find the driver of the Bosch Rexroth L20 PLC to select. There are several drivers available from several manufacturers such as Siemens, Allen Bradley, ABB, but nothing related to Bosch Rexroth PLC.
My question is: What is the description of the driver's communication Bosch Rexroth L20 PLC available on the manufacturers HMI sofwares ?

Thank you.
