ICF-1180I Series Quick Installation Guide Edition 8.0, February 2017 Technical Support Contact Information www.moxa.
Introduction There are two variations of PROFIBUS protocol, PROFIBUS DP (Decentralized Peripherals) and PROFIBUS PA (Process Automation). PROFIBUS PA is used with applications for which the end device needs a power supply from the PROFIBUS PA device and where an intrinsic safe mechanism is also required. Due to the power supply criteria, the number of attached devices is limited. PROFIBUS DP is used in production automation and when centralized controllers are used to manage the system.
PROFIBUS Fail Safe When the PROFIBUS device malfunctions or the serial interface fails, it will generate electrical noise that can cause bus failure. Traditional media converters will let the noise signal pass through the fiber and on to the other converter, disrupting data communication between the two buses and eventually causing communication to cease across the entire system. When this occurs, engineers will not be able to easily locate the failed device because the entire PROFIBUS network is down.
Using Remote Fiber Diagnosis: Set DIP switch SW8 to the ON position on any ICF-1180I converter and then look at the Ready LED status. A flashing green Ready LED indicates that the Fiber Test has finished. The P1 (Fiber port) LED indicates which side (Tx or Rx) is causing the problem. If there are no fiber connection errors in the entire topology, the related LEDs will shine green or remain OFF. If the fiber connection error is adjacent to the converter, the status will also be indicated by the P1 LEDs.

Mounting The aluminum DIN rail attachment plate should be fixed to the back panel of the ICF-1180I when you take it out of the box. If you need to reattach the DIN rail attachment plate to the ICF-1180I, make sure the stiff metal spring is situated towards the top, as shown in the figures below. STEP 1: Insert the top of the DIN rail into the slot just below the stiff metal spring. STEP 2: The DIN-rail attachment unit will snap into place as shown below.
Wiring the Redundant Power Inputs STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals. STEP 2: To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connector. STEP 3: Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on the ICF-1280I’s top panel.
Federal Communications Commission Statement FCC: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. 2. This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. ATEX and IECEx Information 1. 2. 3. 4. 5. Certificate number ATEX: DEMKO 14 ATEX 1384X IECEx: IECEx UL 14.
L: The length of the fiber optic cable in kilometers. N: The number of converters in the system. A and B: Parameters determined by the transmission speed. Note: To avoid frame conflicts, we recommend setting the PROFIBUS command retry limit ≥ 3, and the slot time < 262128. DIP Switch Settings There are 8 DIP switches on the top panel of the ICF-1180I. The factory default setting for all DIP switches, except SW5, is OFF. Transmission Speed (kbps) Auto (default) 12000 6000 3000 1500 500 187.5 93.75 45.45 19.
LED Indicators There are 7 LEDs on the front panel of the ICF-1180I.
Troubleshooting LED Indicators and Fiber Test LED Ready Color Flashing green Description Fiber diagnosis finished Status/Troubleshooting At least one converter is in Fiber Diagnosis mode; Check PROFIBUS master settings; Tx and Rx cables crossed Flashing Detecting No PROFIBUS node; red baudrate No PROFIBUS signal received; Tx and RX crossed over; Baudrate setting is incorrect.
Fiber Signal Intensity Diagnosis In some circumstances you may need to measure the receive level of fiber optic channels P1 and P2 with a voltmeter, which can be connected while the device is operating (doing so will not affect data transmission). The measurement can be taken with a voltmeter and read on a PLC that uses floating high impedance analog inputs, which allows you to do the following: • The incoming optical power to be recorded for later measurement (e.g., to indicate aging or damage).
When taking measurements, use a standard ungrounded, high-resistance voltmeter. The internal resistance of the measurement sockets is approximately 30 kΩ. Keep in mind that you must not connect the measurement sockets or reference potential to the ICF housing. • Multi-mode: ICF-1180I-M-ST • Single-mode: ICF-1180I-S-ST NOTE These charts are not suitable for use with a Remote Fiber Diagnosis test.
