GE IS215VCMIH2C VME Bus Master Controller

GE IS215VCMIH2C VME Bus Master Controller Board

Product Introduction

The IS215VCMIH2C works as the central communication hub in a GE Mark VI control rack. This board handles all data exchange between the main processor and I/O boards. Additionally, it connects the system to the IONet control network. You can use it in simplex or TMR configurations.

Specifically, the IS215VCMIH2C manages board IDs and terminal board assignments. It also acts as the VME bus master in both control and I/O racks. Therefore, this component is critical for system uptime.

Mechanical & Environmental Features

This board uses a standard 6U form factor. Its compact design fits into Mark VI racks without modifications. The operating temperature range supports harsh industrial environments. Furthermore, the conformal coating protects against humidity and dust.

Additionally, the IS215VCMIH2C includes indicator LEDs for quick diagnostics. You can monitor run, fail, and status conditions at a glance. A reset button on the front panel allows manual rebooting.

Installation Guidelines

First, always power down the rack before inserting or removing the IS215VCMIH2C. Next, align the board with the VME backplane guides. Push it firmly until the connectors seat properly. Then, secure the front panel screws.

After installation, connect the IONet cables to the appropriate ports. Use the RS-232C port only for local debugging. Finally, restore power and check the LED status. The Run LED should light up steady.

Moreover, keep at least one spare IS215VCMIH2C on site. A failure of this board stops all I/O communication. Downtime can be expensive, so spares are a smart investment.

Frequently Asked Questions (FAQ)

1. Can I use the IS215VCMIH2C in a simplex system?
Yes, it works perfectly in simplex setups. For instance, when all I/O mounts in the same VME control rack, no distant I/O racks are needed.

2. What happens if the board fails during operation?
The IONet communication stops immediately. Therefore, we strongly recommend keeping a spare IS215VCMIH2C on hand to minimize downtime.

3. Does this board support triple modular redundancy (TMR)?
Yes, it supports TMR systems. The three IONet ports (R, S, T) each connect to a separate control channel for full redundancy.

4. What voltage does the IS215VCMIH2C require?
It requires only +5 V dc power. The backplane provides this voltage automatically. No external power supply is needed.

5. How do I confirm the board is working after installation?
Check the Run and Status LEDs. The Run LED must be solid green. Additionally, each IONet port should show active TX/RX flashes when communicating.
