Product Introduction
The 8507-BI-DP acts as the communication gateway for PAC8000 I/O assemblies. It collects cyclic input data and transmits host output commands over PROFIBUS-DP to process controllers. This module stores configuration in non‑volatile memory and returns extended diagnostic data. It supports HART pass-through for smart field instruments and can run in redundant pairs to reduce single-point failure risk.
Installation & Configuration Guide
Preparation (10 min)
Lock out 24 VDC rack power. Locate the 8701-CA-BI carrier on DIN rail. Download the matching GSD file for your PROFIBUS configuration tool. Record existing node address before removing any hardware.
Removal (5–10 min)
Release the module retention clips on the carrier. Pull the BIM straight outward without bending backplane pins. Photograph the carrier slot and module orientation before removal.
Installation (10 min)
Align the 8507-BI-DP with the carrier edge connector. Press until retention clips lock fully. Confirm the module sits flush and does not shift under light side force.
Power-On & Test (10 min)
Restore 24 VDC power. Check module status LEDs. Import the GSD file and assign the PROFIBUS node address. Download the I/O configuration from the DP master. Verify cyclic data exchange and diagnostic reporting.
Troubleshooting Quick Reference
- No module power LED: Check 24 VDC supply at carrier terminals; verify fuse integrity on carrier.
- PROFIBUS communication failure: Confirm node address matches master project; check bus termination resistor at line endpoints.
- Missing I/O data: Verify GSD file revision; confirm all PAC8000 I/O modules are seated on the same carrier.
- HART pass-through not working: Confirm DP-V1 is enabled in master settings; validate HART instrument wiring.
- Frequent watchdog resets: Review bus cable length against baud rate limits; reduce electrical noise on DP wiring.
Dimensions, Mounting & Wiring Notes
Overall dimensions: 35 mm × 100 mm × 115 mm. Unit weight is approximately 300 g. It mounts exclusively on the 8701-CA-BI carrier, which clips to standard DIN rail. Use shielded twisted-pair PROFIBUS cable. Install 120 Ω termination resistors only at the two physical ends of the DP bus. Keep DP wiring separated from high-current VFD and motor cables.
FAQ
Q: Can I use this module without the 8701-CA-BI carrier? A: No. The carrier provides railbus power and backplane connections for PAC8000 I/O modules. The BIM cannot operate standalone.
Q: I want to run redundant BIMs. Does one carrier support two modules? A: Yes. The 8701-CA-BI carrier accepts a redundant BIM pair. The primary and backup modules continuously monitor each other’s health.
Q: What is HART pass-through on this BIM? A: It lets the PROFIBUS DP master send HART commands to smart 4–20 mA field devices connected to PAC8000 analog modules. You can read device tags and perform calibration remotely.
Q: Is this module rated for hazardous area installation? A: Yes. It carries ATEX and IECEx certification for use in classified hazardous zones, subject to full system assembly compliance.
Q: Is this unit new factory sealed? A: Stock status varies. Confirm condition at quote time; new surplus, tested refurbished options are available.
Q: What warranty applies to this spare? A: 12-month standard warranty. Function verified under controlled test conditions; warranty excludes field wiring and field instrument faults.
Q: I’m wondering if I can mix different PAC8000 I/O module types on the same carrier. A: Yes. Analog input, analog output and digital modules can coexist on one carrier, up to the maximum of 24 total modules.
