1. Overview

1.1. Operation

The WC45i-GW-485 supports all remote WAVECONTACT Endpoints. This allows all remote sensor data to be available in Modbus format.

l The register data from remote sensor Endpointsis available by requesting the remote

Endpoint’s Modbus Slave ID and register address from that Endpoint’s register map.

l The WC45i-GW-485:

l responds with the most recent copy of the data from the remote Endpoint. l automatically times out data from a remote Endpoint it stops receiving data for.

1.1.1. Remote WC45i-GW-485s and Non-sleeping Radio Only Endpoints

l Pre-configured remote Endpoints forward their set of registers to the Modbus Gateway on

a pre-defined schedule (1 minuteto 5 minutes is typical).

l The register data is then buffered in the Gateway and can be read by the RTU at any

time.

l If a Modbus request is received by the WC45i-GW-485 for a Modbus ID and address where

buffered data does NOT exist but the Modbus ID is known, the Modbus request is forwarded to the remote Modbus Endpoint over the WAVECONTACT network.

l The response is returned to the RTU.

l If a request for multiple registersis issued by the RTU AND if the WC45i-GW-485 does

NOT have all registered data buffered, an exception is returned.

l The system will NOT combine buffered and transparent data within a single Modbus

response.

1.1.2. Remote WC45i-GW-485 Endpoint Re-Scan

It is possibleto cause a remote WC45i-GW-485 to re-scan for attachedModbus devices by writing to one of the Gateway’s configuration registers.

l This is useful to discover a Modbus device that is added to an existing Modbus Endpoint. l The scan may be initiated by one of these methods:

l If the radio address of the Gateway is known, writing this address to Gateway register

3000 will result in a scan.

l If the ModbusID of one of the already registered devices attached to a WC45i-GW-485 is

known, a scan is started by writing the ID to Gateway register 3002.

10. Remote Shutdown (RSD) and Local Digital Output Control

The WC45i-GW-485 Modbus Gateway supportsInternalLogic Control capabilitywhich enables the Gateway to control output relays on the WC40i-MB-RSD Modbus Endpoint or WC40iCOUNT.

Note: The WC40i-MB-RSD Modbus Endpoint bundle includes the WC40i-MB and the WC40i-RSD products.

l The WC45i-GW-485 receives data from multiple remote Endpoints. l The data is used from those remote Endpoints to set the relay output on one or more

remote WC40i-MB-RSD or WC40i-COUNT.

l An example of the topologyis shown in Figure 46.

Note: See Connections (on page 11) for port locations.

Use the Remote Shutdown Configuration (on page 46) procedure to control the output relays.

10. Remote Shutdown (RSD) and Local Digital Output Control

Important!: If one or moreof the Endpoints time-out or does not exist, the relay is de-

energized. If this option is NOT selected, then an Endpoint that is not installedor fails to check in is ignored and the relay is energized using logic only from the units that are active.

6. Optional: Click the Latch De-Energized check box so the rules may only de-energize the

relay.

Note: For the relay to be energized again, a Modbus write from a PLC to the Gateway for the destination WC40i-MB-RSD or WC40i-COUNT relay must occur. This is useful if manual intervention is required before the relay is energized after an event. In 10, a Modbus coil write to Slave ID 5 relay channel 1 (which is register 1) is required to energize the relay.

11. Slave Register Remapping

The Gateway allows any of the remote register data to be remappedto a single block of registers available at the Gateway’s Slave ID.

Note: The default is 247.

l This is useful for collecting a subset of register data from multipleEndpoints and making it

readable in a single blockof registers.

l A maximum of 750 registerscan be remapped to the Gateway’s Slave ID starting at register

5000.

Procedure

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