CSH01.1C-CO-EN1-ENS-MEM-S1-S-NN-FW

The CSH01.1C-CO-EN1-ENS-MEM-S1-S-NN-FW is a plug-in control section released within the CSH Advanced Controllers series from Bosch Rexroth Indramat. The module serves as the communication and logic interface inside multi-axis drive assemblies, forwarding commands between motion controllers and field devices in automated production lines. By integrating fieldbus handling, serial diagnostics, and local pulse evaluation into a single board, it reduces cabinet wiring and supports fast reconfiguration during commissioning and maintenance.

Fieldbus traffic is terminated on a D-Sub 9-Pin connector that complies with the CiA pinout used in both CAN-based networks. An internal selector sets the operating protocol; with the switch in the up position the board registers on the bus as CANopen, while the down position retains all wiring yet changes to DeviceNet signaling. For service technicians, a dedicated RS232 interface supplies command-line access to parameters and firmware downloads. Discrete inputs are sampled with a maximum pulse width of 100 ms, preventing loss of slow sensor edges such as mechanical limit switches. During continuous operation the electronics consume only 7.5 W, allowing dense stacking of multiple controllers without exceeding enclosure thermal budgets.

Power-up characteristics and network versatility complete the hardware profile. At startup the board briefly demands 4 A of inrush current, so upstream fusing must tolerate that surge before the load settles to its steady draw. Once initialized it can reside on DeviceNet segments with the same address range used when configured for CANopen, simplifying spare management in mixed systems. Firmware, diagnostic LEDs, and mounting mechanics are identical across the CSH Advanced Controllers family, enabling quick substitution with other variants supplied by Bosch Rexroth Indramat without altering the wiring harness or PLC project.
