CC-IP0101 in Stock | Honeywell Experion C300 Series

Description

Product Introduction

The Honeywell CC-IP0101 is the Profibus DP communication module that plugs into a C300 controller rack. If you’ve got a hybrid plant running Honeywell DCS on top of Profibus-enabled field devices—Siemens drives, Endress+Hauser transmitters, the usual suspects—this is the card that translates between them.

It mounts directly on the C300. No external gateway required. The module handles the Profibus master protocol while the C300 handles the control logic. We’ve seen these in refineries and chemical plants where the DCS needs to talk to motor control centers over a serial bus. It’s reliable but finicky about termination and baud rates.

Key Technical Specifications

Compatible Replacement Models

The CC-IP0101 is still in Honeywell’s active catalog, but there are hardware revisions and alternatives depending on your network topology:

• ✅ Drop-in Replacement: CC-IP0101 (same part number). There are functional revisions (e.g., Rev 1, Rev 2). A newer revision will drop in but may require a firmware update on the C300 controller. Check your current rev against the replacement. If you’re going from Rev 1 to Rev 2, expect a 30-minute flash and config verification.
• ⚠️ Software Compatible: CC-IP0102. This is the redundant version of the module. It requires a redundant C300 pair and specific licensing. It will work in a non-redundant slot physically, but you won’t get the redundancy benefit, and the software may flag a mismatch. We advise sticking to the IP0101 for simplex applications.
• ❌ Hardware Incompatible: CC-PFB801. This is an older Series 800 Profibus module. It uses different termination blocks and wiring. You cannot plug it into a C300 rack without an adapter base, which Honeywell doesn’t sell. If you’re migrating from TDC 3000 or Scan 3000, you’re looking at a full rewiring job.

Frequently Asked Questions (FAQ)

Q: What’s the maximum number of Profibus devices I can connect?
The CC-IP0101 supports up to 125 devices per segment, but that’s theoretical. In practice, with 12 Mbps baud rate and long cable runs, you’ll start seeing timing issues past 50-60 devices. We typically recommend segmenting larger networks with repeaters or adding another CC-IP0101 if you’re pushing past 80 devices.

Q: Can I use this module with a redundant C300 pair?
Yes, but you need two modules—one per controller—and you must use the CC-IP0102 (redundant version). The IP0101 is simplex only. If you plug an IP0101 into a redundant pair, the standby controller will report a communications fault. To be frank, we’ve seen sites try this and end up with failover issues during plant upsets.

Q: How do I terminate the Profibus line on the CC-IP0101?
Profibus requires termination at both ends of the segment. The CC-IP0101 does not have a built-in terminating switch. You need an external Profibus connector with an integrated terminating resistor—the standard Siemens 6ES7 972-0BA12-0XA0 style with the “On/Off” switch works fine. Set it to “On” if this is the last device on the bus.

Q: My module shows “Bus Fault” but the wiring looks correct. What’s next?
Check baud rate first. The module auto-detects, but if the master and slave are trying to sync at different speeds during startup, you’ll get a fault. Force the baud rate in the C300 configuration to match your slowest device. Also, verify shield grounding. Profibus wants the shield grounded at one end only to avoid ground loops. We’ve fixed more “faulty” modules by moving a ground wire than by replacing hardware.

Q: Does the CC-IP0101 store its configuration?
No. It’s a “dumb” interface. All configuration data—device addresses, GSD files, baud rate—is stored in the C300 controller. If you swap the module, the controller downloads the config on boot. This is actually helpful; you can replace a failed module without a programmer, assuming the controller config is intact.

Q: What’s the difference between CC-IP0101 and CC-IP0102 besides redundancy?
Hardware is nearly identical. The IP0102 has a second backplane connector for the redundant link. Functionally, the IP0102 runs a different firmware that handles the failover logic. You cannot flash an IP0101 to become an IP0102. If you need redundancy, buy the correct part.

Q: Can I connect Profibus PA devices to this module?
Not directly. Profibus PA runs at 31.25 kbps and uses two-wire Manchester coding. The CC-IP0101 speaks Profibus DP (RS-485). You need a Profibus DP/PA coupler or link (like the Siemens 6ES7 157-0AA82-0XA0) between the module and the PA segment. The CC-IP0101 sees the coupler as a DP slave.
