Interfaces

CP9xx devices communicate with the devices and systems assigned via various interfaces:
Internal BMS bus (RS-485) for Bender systems such as EDS46.../49..., RCMS46.../49... and

MEDICS®. CP9xx devices can be operated as a master or as a slave. When operated as a master,
requests are answered more quickly. The devices can only be operated on the internal BMS bus.
BCOM (Ethernet) for new and future Bender systems, such as ISOMETER® iso685-D.

Modbus RTU (RS-485) when operated as a master for Bender devices PEM... with restricted

functionality (full functionality of PEM...5 only via Modbus TCP).
Modbus TCP (Ethernet) for Bender universal measuring devices PEM...5
