VariCap system 1 Description The VariCAP system is a set of RGB‐illuminated capacitive switches to control basic functions like ON/OFF. The system communicates with a PLC using MOD‐bus. The PLC reads the status of the switch (stored in a register) and then performs the programmed action. The PLC sends the color of the illumination in return. The color can be set for the Text, Status‐LED and switch indicidually. The switches can be configured in zones, which enables group dimming. This can be usefull when placing the switches on different angle surfaces or group them for certain functions....

VariCap system 2 System overview Basically the VariCap (VC) system is a set of capactive switches controlled by a PLC. The functions of these switches (switch action and backlit illumination) is controlled by a PLC using MOD‐bus protocol. The PLC is the master, the switches just report pressed or not. There is an execption for the keyboard lift cassettes and the relay boards though. The VC system consists of several parts: Part Description 1. VariCap dataconverter communicates to NControl and PLC by MOD‐BUS 2. VariCap Booster reads the switches, controls RGB backlit and switches the relays...

VariCap system 3.1 VariCap switch board The VC switch boards are available in 4 sizes, 1, 2, 3 and 4 switches per board. In the picture above you can see the grid arangement. Of coarse you can mix the boards. Each switch has 3 separate illuminated sections, the touch sensor, the status LED and the text area. All 3 sections can be assigned a color preset and brightness level. The preset information is stored in the booster to which the sensor is connected. The sensor can be used on 4 to 6mm thick glass. The sensor is autotuning upon startup and after 20 seconds. The sensor area (with light...

VariCap system 4 Hardware selection Depending on the configuration you need to make a selection of items below: 1 1x Dataconverter The basis of the system is the Dataconverter. This is the intermediar between the PLC/NControl and pn 0901715 the VC system. Only 1 piece is needed. 2 Qty x VC board Cap switches are available in boards with 1,2, 3 and 4 switches. Each board is one channel on the pn's: booster. Keep in mind when configuring the layout to use grouped switches to keep the qty of boosters small. 8x1 switch = one booster, 8x4 switches = one booster too. 0901717 (1 switch) The...

VariCap system 6 Switch parameters A VC switch has a number of parameters to function. 1. Mod F2 A Modbus address for the switch contact. This is sent to the PLC. 2. Mod F16 A Modbus address for activating the Preset. (0.… 4) This is sent by the PLC 3. Board The VC Booster board and / or VC Stepper to which the switch is connected. number 4. Channel: the address of the switch on the Booster board. See table in appendix. The address depends on the connection to the booster and the position of the switch on the VC touch board. 5. Zone: the brightness / intensity zone to which the switch...

VariCap system 7 Tutorial. 7.1 VariCap switch configuration Below image shows the VariCap tab in the NCOM App. Here all parameters are set for the switches. Just follow the description. 17 Connect the test system and the Ncontrol to the PC with the USB‐RS485 converter cable. Open the NCOM application Select the com port (1) Press [look up], now the Ncontrol and the VC Dataconverter appear in the list (2) Select the VC Data Converter. Go to the [VariCap] tab (3) Select the Modbus address to which the switch data is to be sent. (4) Enter the modbus address to which the preset is sent from the...
