Product Introduction

The DS200SLCCG1 is a serial link controller for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It acts as a gateway between the Mark V backplane and external fieldbus networks such as DeviceNet and Profibus DP.

The SLCCG1 allows a Mark V turbine control system to communicate with third-party devices: remote I/O racks, variable frequency drives, motor starters, and smart instruments. Two independent serial ports can be configured for different protocols. Use it to integrate turbine data into a plant-wide DeviceNet or Profibus network, or to bring external sensor data into the Mark V controller.

Key Selling Points & Differentiators

• Multi-protocol fieldbus gateway – DeviceNet, Profibus DP, Modbus RTU, GE Genius I/O. One board replaces multiple dedicated gateways.
• Two independent configurable ports – Port 1: DeviceNet to remote I/O. Port 2: Profibus DP to VFDs. Or both Modbus. Or one for programming.
• Direct backplane access – I/O data appears as standard Mark V analog or digital points. No extra programming or mapping required.
• DeviceNet slave support – Connect to Rockwell/Allen-Bradley PLCs. Supports polled, strobed, cyclic, and change-of-state connections.
• Profibus DP slave support – Connect to Siemens, ABB, or any Profibus master. Auto-baud detection. DPV1 acyclic services for parameter access.
• Modbus RTU master/slave – Connect to flowmeters, pressure transmitters, power monitors. Master mode polls up to 32 devices.
• Configuration utility included – Windows software sets protocol, baud rate, and I/O mapping. No ladder logic programming required.
• QC includes protocol conformance testing – Verified with Rockwell DeviceNet scanner, Siemens Profibus master, Modbus poller.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SLCCG1 and using a separate external gateway?
A: The SLCCG1 mounts inside the Mark V rack and has direct backplane access. No external power supply, no additional wiring (except fieldbus cable). Data appears as native Mark V I/O. External gateways require analog or serial connections and separate programming.

Q: Can I use the SLCCG1 to connect a Mark V to a modern PLC (e.g., ControlLogix)?
A: Yes—use DeviceNet (Port 1). Configure the SLCCG1 as a DeviceNet slave, ControlLogix as master (with 1756-DNB scanner). Data exchange up to 512 bytes each direction. For Ethernet/IP, use DS200PLFMG1 (Ethernet).

Q: How do I configure the board?
A: Connect PC to RS-232 programming port (front panel). Run included Windows software. Select protocol for each port, set baud rate and node address, map I/O data to backplane addresses. Save configuration to board’s flash memory. No DIP switches—all software configurable.

Q: What is the maximum I/O data size?
A: 512 bytes input, 512 bytes output total across both ports. Example: Port 1 DeviceNet: 256 bytes input, 256 bytes output. Port 2 Modbus: 256 bytes input, 256 bytes output. Total not to exceed 512 each direction.

Q: Does the SLCCG1 support Profibus DPV1?
A: Yes—acyclic services for reading/writing parameters. Use DPV1 to configure slave devices (VFD parameters, instrument configuration) without affecting cyclic I/O.

Q: What is the scan rate for DeviceNet?
A: Depends on baud rate and I/O size:

• 125 kbps, 128 bytes: 5 ms
• 250 kbps, 256 bytes: 5 ms
• 500 kbps, 512 bytes: 10 ms
  Cyclic I/O configurable (1–100 ms). Change-of-state produces immediate updates.

Q: What QC tests are specific to the SLCCG1?
A: Nine tests:

1. DeviceNet conformance: tested with Rockwell 1756-DNB scanner, all I/O sizes, 24 hours
2. Profibus DP conformance: tested with Siemens S7-1200 master, all baud rates, DPV1 acyclic
3. Modbus RTU: master mode polling 32 slaves, 115.2 kbps, 24 hours
4. Port isolation: 1800 VAC between ports and backplane
5. Data mapping: verify 512 bytes input/output to backplane
6. Configuration save/recall: power cycle, verify config retained
7. LED test: all status LEDs
8. Temperature: 0°C to +60°C operation
9. Burn-in: 72 hours at +60°C, continuous fieldbus traffic

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, double-wall box with “ESD SENSITIVE,” “FRAGILE” labels. Configuration software on CD (USB drive option available). RS-232 programming cable included. Termination resistors included. Each board ships individually.
