Warning
|
Danger to life due to electrical shock
There is a risk of fatal electrical shock when working on devices in the switch cabinet with 230 V mains voltage. ▷ Operations in the switch cabinet may only be carried out by qualified electricians. ▷ Before carrying out any operations in the switch cabinet, switch off the power supply properly. |
|
Caution
|
Damage to the device due to overheating
The ambient temperature in the switch cabinet must not exceed the maximum permissible operating temperature. ▷ Keep ventilation slots clear. ▷ Observe the installation clearances. ▷ Mount the device in the intended orientation. ▷ Do not place appliances with high input power directly next to each other. ▷ Regularly remove dust and dirt from the area around the appliance. |
Connecting RevPi Con Modules #
|
Caution
|
Damage to the device due to installation under voltage supply
While the RevPi device is connected to a power source, no other devices may be connected or disconnected, as this may cause damage to the devices. ▷ Do not connect the power supply until all other devices are connected correctly. ▷ Switch off the power supply before disconnecting a device from the system. |
|
Caution
|
Damage to the devices due to mix-up of the plug connectors
▷ Only connect RevPi I/O modules and RevPi gateways to the system via the black PiBridge plug connectors. ▷ Only connect RevPi Con M-Bus and RevPi Con CAN to the system via the gray ConBridge plug connectors. |
RevPi Con modules can only be connected on the right-hand side of the following base modules.
| Left Side | Base Module | Right Side |
|---|---|---|
5 × RevPi I/O module |
RevPi Connect SE |
1 × RevPi Con CAN + 1 × RevPi Con M-Bus |
5 × RevPi I/O module or |
RevPi Connect+ |
1 × RevPi Con CAN + 1 × RevPi Con M-Bus |
The RevPi Con modules are connected to a RevPi Connect S/SE/+ via gray ConBridge plug connectors and supplied with power. A plug connector is included in the scope of delivery of a RevPi Con module or can be ordered via the store (item no. 100297).
▷ Make sure that all devices are disconnected from their power supplies.
▷ Mount the RevPi Con module to the right of the RevPi Connect S/SE/+ on the DIN rail.
▷ Connect the RevPi devices with the gray ConBridge plug connector^] on the top of the housing.
Connecting RevPi Con CAN to the CAN Bus #
You can connect the RevPi Con CAN to the CAN bus using the X2 connector.

Avoid reflections #
Reflections can interfere with your data communication. They can occur anywhere where there is a physical irregularity, e.g.
-
At the end of a line
-
At the transition of a line
-
On a damaged cable
If your signal encounters such an irregularity, part of the signal is reflected and it moves in both directions on the transmission line. The same signal thus reaches the same receiver twice.
However, you can avoid reflections by making a few simple preparations:
▷ Activate the terminating resistor for devices located at the beginning and end of the line.
▷ With your RevPi Con CAN, you must connect pins 1 and 2 and pins 3 and 4 with a wire bridge.
▷ Check whether your cables are damaged.
▷ Make sure that your cables are laid straight.
