1 converter for CAN-based systems (termination device) Data sheet _en_01 PHOENIX CONTACT Description The converter enables the conversion from CAN-based systems to fiber optics. The device supports the DeviceNet and CANopen protocols. As a result of the simple and interference-free networking via fiber optics, bus cable short circuits only affect the actual potential segment concerned. This increases overall availability and improves flexibility in terms of the bus topology. This prevents the negative effects of equipotential bonding currents and electromagnetic interference on the bus cables. The termination device is ideal for point-to-point connections. In conjunction with the PSI-MOS-DNET/ 850 T T-coupler, branch lines and star and tree structures can be established. Features Automatic data rate detection or fixed data rate setting via DIP switches Data rate up to 1 Mbps Integrated optical diagnostics for continuous monitoring of fiber optic paths Floating switch contact for leading alarm generation in relation to critical fiber optic paths Cascadable star and tree structures can be created using bit retiming. Electrical isolation between all interfaces Supply voltage and data signals routed through a DIN rail connector Redundant power supply possible Can be combined with a PSI copper repeater, segment coupler, and bridge in a modular way using DIN rail connectors WARNING: Explosion hazard when used in potentially explosive areas The module is a category 3 item of electrical equipment. Follow the instructions provided here during installation and observe the safety instructions. Make sure you always use the latest documentation.

Check the data rate set via the DIP switches. Check the connected master and its bus parameters (e.g. data rate). Check connected data cables to ensure the connection and polarity are correct. Check the network termination. Check the connected master and its bus parameters (e.g. timing). Check the network and supply voltage for coupled interference _en_01 PHOENIX CONTACT 13

14 LED indicators of the interface The quality of the path is determined using the incoming optical power P opt and displayed using the LED bar graph. LED Receive signal Optical power P opt signal Green Receiving power is very good Significantly greater than system reserve Green Receiving power is good Still greater than system reserve Yellow Receiving power is critical P opt has reached the system reserve. ERR Red Receiving power is insufficient, broken fiber As soon as the system reserve is reached, only the yellow LED remains lit. At the same time the alarm relay drops out and opens the switching output. Data communication is still possible. 7.5 Interfaces The device has three interfaces for the bus signal: Electrical interface (COMBICON) port A DIN rail connector (TBUS) All interfaces communicate with one another with equal rights. If a signal is present at one of the interfaces, this signal is also available to all other interfaces.

ON = DIP 1 DIP 2 DIP 3 DIP 4 Data rate [kbps] Autobaud Mixed operation of different converters As a rule, the PSI-MOS-DNET/ converter and devices from the older PSI-MOS-DNET CAN/ series can be used together. The following conditions must be met: Max. data rate 800 kbps Only Fast operating mode supported No redundancy operation Maximum distances HCS fiber: 2300 m Fiberglass 50/125: 2800 m Fiberglass 62.5/125: 3600 m 8.2 Operating mode switching (DIP switch 5) "Extended" (DIP 5 = OFF): The device supports the maximum segment length that depends on the data rate set. The internal bus management is activated, bit retiming is available. The bit delay in the device has a telegram runtime (between 44 and 108 bits, depending on the type of telegram). This operating mode is suitable for physically extensive networks with moderate response times. "Fast" (DIP 5 = ON): Internal bus management is deactivated. When the bit delay is < 1 bit, both as stand-alone device and grouped (modular star coupler), the total size of the network is reduced across all segments. Only electrical isolation and signal amplification occurs between the ports. This operating mode is suitable for small networks with fast response times. In a modular topology, all the devices must be set to the same operating mode. 8.3 Setting the fiber optics type (DIP switch 8) You can use multimode fiberglass (DIP 8 = OFF) or HCS fiber (DIP 8 = ON). 8.4 Termination resistor If the device is used at the beginning or end of a copper segment, the integrated termination resistor must be activated.

The devices are grounded when they are snapped onto the DIN rail (installation according to PELV). This ensures that the shielding is effective. Connect protective earth ground with low impedance. B C 9.1 Mounting as single device Figure 12 Combined assembly Figure 11 Mounting on a DIN rail To avoid contact resistance, only use clean, corrosionfree 35 mm DIN rails according to DIN EN Install an end clamp next to the left-hand module to prevent the modules from slipping. Place the module onto the DIN rail from above. Push the front of the device toward the mounting surface until it audibly snaps into place. The other modules to be contacted are snapped onto the DIN rail next to each other. The DIN rail connector is used to bridge the power supply and communication. For one connection station, plug the DIN rail connectors (TBUS) together (order no , 2 per device). Push the connected DIN rail connectors into the DIN rail. Place the module onto the DIN rail from above. Push the front of the device toward the mounting surface until it audibly snaps into place. A connection station must not consist of more than ten devices. In this case, it is vital to observe the mounting direction of the module and DIN rail connector: snap-on foot at the bottom and connector on the left! _en_01 PHOENIX CONTACT 17
