Technical Parameters & Selection Guide

Selection Criteria: Choose the CS200 when you need distributed I/O with CANopen connectivity, legacy serial device integration, or hot-swap capability. For applications requiring more than 15 I/O points per station, consider cascading multiple CS200 modules or upgrading to BACHMANN's modular I/O systems with higher channel density. Ensure your master controller supports CANopen DS-301 and verify network cable specifications (CAN_H/CAN_L twisted pair with 120Ω termination resistors at both ends).

Advanced Integration Capabilities

Firmware Field-Upgradeable via SDO
Update module firmware through CANopen Service Data Objects without physical access, enabling feature enhancements and bug fixes across distributed installations without production downtime.

Emergency Message Priority Transmission
Critical alarms and fault conditions transmit via CANopen emergency objects with higher priority than cyclic process data, ensuring safety-related signals reach the master controller within guaranteed time windows.

Galvanic Isolation Architecture
Electrical isolation between CANopen network, I/O channels, and power supply circuits prevents ground loops in multi-building installations and enhances immunity to electrical noise from VFDs and welding equipment.

PC-Based Configuration Tools
Graphical software utilities simplify network setup, I/O channel mapping, and parameter management. Export/import configuration files for rapid deployment of standardized machine designs across multiple production sites.

Frequently Asked Questions

Q: How do I connect the CS200 module to my existing CANopen network?
A: Wire CAN_H and CAN_L terminals to your CANopen trunk cable (twisted pair, 120Ω characteristic impedance). Install 120Ω termination resistors at both physical ends of the network. Set a unique node address (1-127) via rotary switches or software configuration. The module auto-detects baudrate from 10 kbit/s to 1 Mbit/s during power-up.

Q: What is the maximum I/O capacity per CS200 module and can I expand it?
A: Each CS200 supports 15 I/O points in configurable combinations (digital/analog, input/output). For applications requiring more channels, deploy multiple CS200 modules on the same CANopen network with unique node addresses. A single CANopen master can manage up to 127 slave nodes, providing scalability to 1,905 I/O points.

Q: Does the CS200 support remote monitoring and diagnostics?
A: Yes. The module provides comprehensive diagnostics via CANopen SDO access, including power supply voltage, communication error counters, I/O channel status, and configuration parameters. LED indicators on the front panel show power status, network activity, and fault conditions for local troubleshooting.

Q: Can I integrate RS232/RS485 devices while using CANopen communication?
A: Absolutely. The CS200 operates as a multi-protocol gateway, allowing simultaneous CANopen network communication and serial device connectivity. Connect barcode scanners, RFID readers, or legacy HMI panels to RS232/422/485 ports while the module exchanges I/O data with the CANopen master controller.

Q: What configuration is retained during power loss?
A: All parameters stored in FLASH memory persist through power cycles: node address, baudrate settings, I/O channel assignments, serial port configurations, and heartbeat timings. No battery backup required, eliminating maintenance costs associated with battery replacement in distributed installations.

Q: Is the CS200 suitable for outdoor or harsh environment installations?
A: The module is rated IP20 for panel mounting in controlled environments. For outdoor or washdown applications, install the CS200 inside a NEMA 4X/IP65-rated enclosure with appropriate environmental sealing. Operating temperature range of -25°C to +60°C covers most industrial applications including unheated warehouses and tropical climates.
