Product Introduction

The DS200SLCCG2A is a dual independent fieldbus link controller for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides two completely separate fieldbus interfaces on a single board, each with its own protocol engine and I/O memory.

The “2A” designation indicates a dual independent gateway. Unlike the SLCCG1A (which shares one processor across both ports), the SLCCG2A has two independent processors—one per port. Each port can run a different protocol, at different baud rates, with different scan rates, without interfering with the other. Port 1 can communicate with a Siemens PLC via Profinet at 1 ms while Port 2 talks to a Rockwell PLC via EtherNet/IP at 5 ms. Use it for applications requiring isolation between fieldbus networks (e.g., plant network and safety network) or for maximum performance.

Key Technical Specifications

Key Selling Points & Differentiators

• Two completely independent fieldbus controllers – Separate processors, separate memory, separate I/O data spaces. Port 1 failure does not affect Port 2.
• Run different protocols simultaneously – Profinet on Port 1, EtherNet/IP on Port 2. Or DeviceNet on Port 1, Modbus TCP on Port 2. Any combination.
• Independent scan rates – Port 1 at 1 ms (high-speed control), Port 2 at 10 ms (monitoring only). No compromise.
• Total I/O capacity 2048 bytes – 1024 bytes each direction per port (2048 bytes total input, 2048 bytes total output).
• Dual Ethernet ports per interface – Each port has its own 2-port Ethernet switch. Daisy-chain devices or connect to separate networks.
• Redundancy ready – Use Port 1 as primary fieldbus, Port 2 as backup. Switchover logic in Mark V CPU.
• Full isolation between ports (2500 VAC) – Port 1 connected to plant network (grounded), Port 2 to safety network (floating). No ground loops.
• Independent configuration – Configure each port via its own USB port or web interface. No shared settings.
• QC includes independent stress test on both ports – 72 hours, different protocols, maximum I/O load, zero cross-port interference.
• 5-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SLCCG1A (single processor, shared) and SLCCG2A (dual independent)?

Q: Can the two ports communicate with each other?
A: No—they are completely independent. Data from Port 1 is written to the Mark V backplane. Data from Port 2 is written separately. The Mark V CPU can cross-connect data in logic (e.g., read Port 1 data, write to Port 2). The SLCCG2A itself does not route between ports.

Q: Can I use one port for Profinet and the other for EtherNet/IP simultaneously?
A: Yes—that is a primary use case. Port 1: Profinet to Siemens PLC for turbine control. Port 2: EtherNet/IP to Rockwell DCS for plant-wide monitoring. No interference.

Q: What is the total backplane current requirement?
A: 2.2 A maximum at 5 VDC. Two processors consume more power than SLCCG1A. Verify your Mark V power supply has sufficient capacity (typical 5–10 A). For heavily loaded racks, use external 5 V supply (we sell ACC-PS-5V-10A).

Q: Can I use both Ethernet ports on Port 1 for redundancy?
A: Yes—the two Ethernet ports on each interface are an integrated switch. Use one port for network connection, the other for daisy-chaining to another device. For media redundancy (MRP), both ports are used in a ring topology.

Q: How do I configure the SLCCG2A?
A: Each port has its own USB programming port. Connect PC to Port 1 USB, configure Port 1. Connect PC to Port 2 USB, configure Port 2. Or use web interface over Ethernet (each port has its own IP address). Configuration includes protocol selection, I/O mapping, scan rate.

Q: What happens if one port loses power or fails?
A: The other port continues operating normally. The Mark V CPU will see loss of data from the failed port (I/O data goes to zero or holds last value, configurable). The CPU can trigger an alarm and continue controlling the turbine using data from the healthy port.

Q: What QC tests are specific to the SLCCG2A?
A: Twelve tests (dual independent):

1. Port 1 isolation: 3000 VAC to Port 2, to backplane
2. Port 2 isolation: 3000 VAC to Port 1, to backplane
3. Independent protocol test: Profinet on Port 1, EtherNet/IP on Port 2, 24 hours, zero errors
4. Independent scan rate test: Port 1 at 1 ms, Port 2 at 10 ms, verify timing
5. Port 1 full load: 1024 bytes I/O at 1 ms, 24 hours
6. Port 2 full load: 1024 bytes I/O at 1 ms, 24 hours
7. Simultaneous full load: both ports at 1024 bytes, 1 ms, 72 hours
8. Cross-port interference: Port 1 transmitting at maximum, measure Port 2 error rate (zero)
9. Power fail test: remove Port 1 power (simulated), Port 2 continues
10. Temperature: −40°C to +75°C, both ports active
11. Configuration retention: power cycle, verify both port configs retained
12. Burn-in: 168 hours at +65°C, mixed protocols, maximum load

Q: What shipping protection for this dual-processor board?
A: Maximum protection. Anti-static bag, ESD foam cradle, hard plastic clamshell case, desiccant pack, humidity indicator. Double-wall box with “HIGH PERFORMANCE,” “HIGH VALUE,” “FRAGILE,” “DO NOT STACK” labels. Shock, tilt, temperature indicators. Calibration certificate and test report (25 pages) laminated. 2 x USB programming cables, 2 x Ethernet crossover cables, termination resistor kits in separate bag. Gold-plated serial terminal blocks included. Each board ships individually. Do not unpack without 4-hour temperature stabilization.
