Overview

The OP1S (Operator Panel) is an optional input/output unit that can be used to parameterize the converters. Parameterization is menu driven; the parameter number is selected and the parameter value is entered. The displays are in plain text.

The descriptions of the parameters and parameter values as well as the text displays are included in English, German, French, Spanish and Italian as standard.

The OP1S is equipped with non-volatile memory and is able to save complete parameter sets permanently. It can therefore be used to archive parameter settings and to transfer parameter sets from one unit to another.

The memory capacity is sufficient to store, for example, 5 data sets from CUMC boards. It is not possible to save data sets from technology boards (e. g. T100, T300).

There is a 9-pin Sub-D connector on the rear of the OP1S. This is used for connection of the power supply as well as for communication with the connected units.

The OP1S operator panel is directly plugged into the Sub-D socket of the PMU operator control and parameterization panel and screwed into the front cover. The OP1S operator panel can also be used as a remote operation device. The cable between the PMU and the OP1S can be up to 200 m in length. In the case of distances greater than 5 m, a generally available 5 V power supply unit with a current of at least 400 mA must be connected at the OP1S end.

The communication between the OP1S and the converter to be operated takes place via a serial interface (RS 485) with USS protocol. In this communication, the OP1S assumes the role of the master. The connected converters operate as slaves. The OP1S can be operated at transmission rates of 9.6 kbits/s and 19.2 kbits/s.

It can communicate with up to 31 slaves (addresses 1 to 31).

It can therefore be used either with a point-to-point connection (for operating one converter) or in a bus configuration (for operating several converters).
