4.3MRLDS Gateway

4.3.1MRLDS Gateway Setup on I/O Network

Modbus versions of the MRLDS must be connected to the 810-3040 MRLDS Gateway. The MRLDS Gateway can be mapped in either of two ways: it can be set up on I/O Net as an IRLDS application or as a 16AI board. Select by setting the Gateway’s dip switch #5 to the OFF or ON position (Figure 4-6).

SELECT I/O NET MODE

OFF = IRLDS

ON = 16AI

ON

OFF = IRLDS ON = 16AI

Figure 4-6- I/O Network Modes

4.3.2Gateway Connections

Up to 12 MRLDS units may be connected to the Gate- way board (P/N 810-3040). The Gateway board can inter- face with a site controller as a 16AI or as an IRLDS. If the site controller is an Einstein or E2, it is recommended to interface them as an IRLDS. Multiple Gateways can be used, each with up to 12 connected MRLDS units.
