Application Fields
The PLC-5/40V is specifically designed for hybrid systems where VMEbus processing and standard PLC control must coexist:
- Aerospace Testing: High-speed data logging from VME instrumentation combined with machine safety logic.
- Semiconductor Fabrication: Precision timing and motion control within cleanroom VME-based tools.
- Defense & Simulation: Real-time environment simulation and hardware-in-the-loop (HIL) testing.
- Large-Scale Manufacturing: Acting as a supervisor for multiple Remote I/O racks across an assembly plant.
Product Usage Instructions
- VME Slot Selection: Ensure the VME chassis provides adequate power (+5V at 3.3A). The PLC-5/40V is a double-height (6U) module and typically occupies a single slot.
- Memory Backup: Check the internal lithium battery (1770-XY) before installation. This battery maintains the user program and data during power cycles.
- Communication Setup: Use the front-panel 8-pin mini-DIN or 25-pin D-shell ports for programming via DH+ or Serial connections.
- I/O Configuration: Configure the Remote I/O (RIO) scanners via RSLogix 5 to recognize local VME memory maps as I/O image tables for seamless data transfer.
- Thermal Management: Ensure the VME rack has forced-air cooling. The PLC-5/40V generates significant heat during high-speed logic execution.
Product Technical Description
The PLC-5/40V (60-0093-01) bridges the gap between open-architecture VME systems and the industrial reliability of Allen-Bradley’s 1785 platform. Technically, it functions as a “dual-port” device; it executes standard ladder logic while simultaneously allowing other VMEbus masters (like Unix or VxWorks-based CPUs) to read and write directly to its data table memory. This allows for extremely low-latency communication between complex computational tasks on the VMEbus and real-time I/O control on the plant floor.
Q&A (Common Questions)
Q: Can I use standard PLC-5 I/O modules with this controller? A: Yes, via the Remote I/O (RIO) port, this controller can manage any standard 1771-series I/O chassis.
Q: What is the difference between the 5/40V and a standard 5/40? A: The “V” stands for VMEbus. While the processing logic is identical, the 5/40V is a circuit board designed to fit into a VME rack rather than a standard 1771 I/O chassis.
Q: Does it support DH+ communication? A: Yes, it features two configurable channels that support Data Highway Plus (DH+) for peer-to-peer networking or Remote I/O for scanner/adapter functionality.
Q: What happens if the battery dies? A: The red “BATT” LED on the front panel will illuminate. If power is lost while the battery is dead, the user program in the SRAM will be cleared.
