3.1.3. Analog Outputs

In (Figure 3), each switch controls the output mode for a pair of outputs.

l The switch on the left sets both Output 1 (AO1) and Output 2 (AO2) to either mA or Volts. l The switch on the right sets both Output 3 (AO3) and Output 4 (AO4) to either mA or Volts. l In mA output mode, the compliance voltage is the Endpoint supply voltage.

3.1.4. Analog Inputs

The Analog Inputs may operate in either Current (0-20mA / 4-20mA) or Voltage (0-5V / 1-5V). The input mode is set usingslide switches inside the WC25i (Figure 3).

Note: Each remote device connected to the Gateway MUST have a unique Modbus Slave ID (1-240). See: Modbus Registers - WC25i (on page 47)

Important!: Verify there are no duplicate Slave IDs in a given network.

The Gateway only caches oneset of data for each Slave ID. A duplicate is overwritten.

d. Clickthe Set button to save the information. e. Optional: In the Node Name text box, enter a name for the Endpoint using a maximum

of 10 characters.

Use the Digital Input Debounce window (on page 60) to designate the digital input Debounce Time to accurately total Digital Input counts.

Note: The Debounce Time is useful when using contacts that may produce extra counts when they

close.

Example: A typical value for a dry contact is 100mS. Any extra counts due to contact bounce within the Debounce Time setting are ignored.

9. Digital Input State Latch

The State Latch feature is used where a fast transition sensed by the WC25i may happen too quickly to be read by the WC45i-Gateway.

The state of one or both of the digital inputsis latched to a value for a configurable number of seconds.

Example: If the Input Channel 1 list box is set to Latch Closed (1) for the 3 seconds entered in the Input Channel 1 or 2 Seconds text box, then any close sensed on the digital input is reported as

closed for 3 seconds even in the input opens in less than 3 seconds.

10. Modbus Registers - WC25i

The WC25i sends data to a WC45i-Gateway. Every check-in period, the sensors are read and data is sent to the Gateway. The Gateway saves

the data under the set Modbus ID in 16-bit registers.

l The data sent to the Gateway is available at the Gateway in registers where it is read by a

ModbusRTU master device.

l The Endpoint must have a unique (to the network it is in) ModbusSlave ID.

l The Gateway usesthisSlaveID to store its unique data.

Note: The terms node and Endpoint are used interchangeably in this document.

Note: This data is accessible at the same Slave ID as the connected Modbus device.
