Mounting and Connecting #
The RevPi was developed for use in a control cabinet. Observe the specifications for the Intended Use and all Safety Instructions.
|
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. |
Carry out the mounting and connection in the following order:
-
Mount the RevPi base module and all expansion modules on a DIN rail.
-
Connect the expansion module via the PiBridge plug connector.
-
Connect all other devices such as sensors and actuators.
-
As the last step connect the power supply.
Configuration #
An expansion module is configured as part of the module configuration of the Revolution Pi system, i.e. a RevPi base module with expansion modules. This is possible via the application PiCtory or, if applicable, directly in the development environment, e.g. via CODESYS.
|
Note
|
CODESYS and PiCtory cannot be used in parallel for configuration. An existing configuration via PiCtory will be overwritten by a configuration via CODESYS. The virtual devices OPC UA Server and MQTT Client can only be used via PiCtory. |
Parameterization #
The following parameters, outputs (OUT) and memory variables (MEM) can be configured:
RelayOutput_1 … 4 (OUT) #
Displays the current status of outputs 1 …4 (bits 0 …3).
-
1: Error at the output (threshold exceeded)
-
0: no error
RelayCycleWarningThreshold_1 … 4 (MEM) #
A threshold value for the number of switching operations can be set for each relay output.
If this threshold value is exceeded, the RevPi RO switches on the red status LED for the respective output and generates a warning at the status bit for the respective relay.
The default value is 0. With a threshold value of 0, no warning is triggered on the status bit and the warning LED remains deactivated.
The threshold values should be selected according to the specifications in the data sheet of the relay module used:
| Type of load | Voltage | Current | Recommended threshold value for warning limit |
|---|---|---|---|
Resistive load |
250 V AC |
3 A |
100 000 |
30 V DC |
100 000 |
||
