V2xx, V5xx Installation Instructions

• Turn power off before opening the controller.
• If the controller has an installed Snap-in I/O module, remove it. Instructions are given in ‘Removing a Snap-in Module’ in your Vision model’s Installation Guide.
• If the controller does not comprise a Snap-in I/O Module, ensure that the I/O connector cap is in place.

Note that the V2xx is shown for representational purposes.

1. Turn power off before opening the controller.
2. If the controller has an installed Snap-in I/O module, remove it. Instructions are given in ‘Removing a Snap-in Module’ in the Vision User Guide.
3. Open the OPLC by inserting a screwdriver into the slots located on the sides of the controller as shown, then carefully prying the cover off.
4. The port’s location is covered by plastic. Remove the plastic covering using a razor cutter to cut through the tabs shown in Figure 1.
5. Locate the J1 and J3 connectors shown in Figure 2.
6. Install the module by placing the module’s connectors onto the controller card as shown in Figure 3. In order to avoid bending the connector pins, exercise appropriate caution. Make sure that the connection is secure.
7. Close the controller by snapping the plastic cover back in its place. If the card is placed correctly, the cover will snap on easily.
8. If required, reinstall the Snap-in Module.

V1040/V1210

1. If the I/O connector cap is in place, remove it.
2. Open the communication module cover shown in Figure 4 .
3. The port’s location, COM 3, is covered by plastic. Remove the plastic covering using a razor cutter to cut through the tabs shown in Figure 1.
4. Install the module by lining up the module’s connectors with those in the controller, and push it into place. See Notes below.
5. Close the controller by snapping the plastic cover back in its place. If the card is placed correctly, the cover will snap on easily.
6. If required, reinstall the Snap-in Module. If there is no Snap-in Module, replace the I/O connector cap.

Note
Your card was supplied with a single screw, and you are installing it in a V1040/V1210, after pushing the module into place, screw it into the hole that is located near the port.

V200-19-ET2 Ethernet COM Port

The V200-19-ET2 Ethernet COM Port is a communication module that enables you to install an Ethernet COM port into compatible Vision controllers. The Ethernet port enables you to implement communications via TCP/IP such as MODBUS over TCP.

Software & Hardware compatibility

The V200-19-ET2 hardware is backward compatible with existing and new Vision series PLCs as listed in the table below. The V200-19-ET2 is supported by the following (or higher) software versions:

Wiring

• Do not touch live wires.
• Unused pins should not be connected. Ignoring this directive may damage the device.
• Double-check all wiring before turning on the power supply.

Ethernet Wiring—General

• Use CAT5 STP (shielded twisted pair) cable.
• Set up the network in accordance with the star configuration shown below.

RJ45 Connector Pin-out

Topology

Star topology is recommended.

Ethernet Connections 

V200-19-ET2 Technical Specifications

• Transmission speed 10/100Mbps
• Network topology Star, based on external hub/switch
• Cable type Category 5 STP (shielded twisted pair) is recommended; UTP (unshielded twisted pair) may also be used
• Connector type RJ45
• Drop line length Up to 100 meters, controller to hub/switch or controller to controller.

V200-19-RS4, V200-19-RS4-X RS485/232 COM Port

V200-19-RS4, V200-19-RS4-X are communication modules that enable you to install compatible Vision controllers with an additional COM port, COM 3. The port may be adapted to either the RS232 or the RS485 standard, via jumpers located on the modules and with the appropriate VisiLogic program settings.
Note that the modules are identical except for isolation:

• ◼ V200-19-RS4 is not isolated
• ◼ V200-19-RS4-X is isolated

Installation instructions begin on page Error! Bookmark not defined..
For specific information on RS485/232 networking, refer to the controller’s user guides and VisiLogic’s Help file.

Component identification RS232 Connector Pin-out

Note that standard programming cables do not provide connection points for pins 1 and 6.
In addition, note that when a port is adapted to RS485, Pin 1 (DTR) is used for signal A, and Pin 6 (DSR) signal is used for signal B as shown in the RS485 pinout.

RS485 Wiring

Note that when a port is set to RS485, you can switch between end devices using either RS232 and RS485 without changing jumper settings. To enable you to do this, do not use flow control signals DTR and DSR.

Caution

• Note that the V200-19-RS4 port is not isolated. If the controller is used with a non-isolated external device, avoid potential voltage that exceeds ± 10V. To avoid damaging the system, all non-isolated device ports should relate to the same ground signal.
• Use shielded, twisted pair cables.
• ◼ Minimize the stub (drop) length leading from each device to the bus.
• ◼ Ideally, the main cable should be run in and out of the network device.
• ◼ Do not cross positive (A) and negative (B) signals. Positive terminals must be wired to positive, and negative terminals to negative.

RS485 Connector Pin-out

RS485 Network Termination Settings

The jumper settings shown below determine whether the controller can function as an end device in a RS485 network. Note that the factory default setting is ON. If the OPLC is not a network end device, set both jumpers to OFF.

RS232/RS485 Jumper Settings

The tables below show how to set a specific jumper to change the functionality of the port. To open the controller and access the jumpers, refer to the installation instructions below.
