PKE12/32/65 1.1 Introduction The PKE-COM-RTU module is used to control the PKE motor or circuit breaker via a programmable logic controller and to record the information from the PKE. The PKE-COM- RTU is connected directly to the PKE12, PKE32 and PKE65. -

PKE65. The trip blocks used, which can be combined with the PKE basic devices, must be of type PKE-XTUA or PKE-XTUWA. For each PKE-COM-RTU, a PKE with PKE trip block can be connected. The following PKE trip blocks of the type "Extended" can be combined with the PKE basic devices PKE12, PKE32 and PKE65. - Page 8 ▶ Set the slave address on the device.

Addressing is performed individually for each PKE via the DIP switches on the respective PKE-COM-RTU module. It is independent of the physical connection (position) in the network. A bus termination resistor is required at the last module on the Modbus line. -

Data (N x 1 Byte) CRC (2 Bytes) Figure 4: Data exchange between master and slave The PKE (slave) only sends a response if it has received a request from the master beforehand. PKE-COM-RTU Modbus RTU communication interface for PKE12/32/65 03/20 MN034005EN... -
Page 13: Structure Of The Master Request
The address of the slave (1 to 63) to which the request goes is set via the DIP switches • at the PKE-COM-RTU. Only the PKE with this address can respond to the request. Address 0 is used as a so-called Broadcast (message to all bus users) from the master. -
