Physical Modbus Interface:
- RS 232C* (Point to Point Interface, 19200 Baud max.)
- RS 485 (2 [3] wire Bus Interface, 19200 Baud max.)
- RS 422 (4 [5] wire Bus Interface, 19200 Baud max.)
All interfaces are connected by a 9-pin D-SUB plug connector. The plug pin assignment and the
interface parameters can be seen in the gateway device manual PKV 30-COS Protocol converter
for CANopen Slave.
NOTE: For operating the gateway PKV30 via RS485 the jumper J5 inside the device has to be
set to position 3-4 and the parameter RTS-Control has to be switched to YES with the COMPRO
tool. See also the "device manual protocol converter for CANopen Slave" and the "Operation man-
ual COMPRO".
Data format Modbus RTU Standard:
There are 3 different modes which can be used.
- Mode 1 contains the measuring value in INT16 , dimension and measuring range of the indi-
vidual measuring points
- Mode 2* only contains the measuring values in INT16 of the individual measuring points.
- Mode 3 contains the measuring value as a decimal number, measuring point No., measuring
point status, dimension and measuring range.
* Basic setting (See Bridge manual Transfer CANopen Slave to MSA AUER at the PKV30-COS)
Parameter setting is made by the comPro program enclosed on a floppy disc. (See operation man-
ual “Project planning and diagnostic program” DOS program.)
