Figure 43 Multicast Group
Enabled
Enables or disables the multicast pipe manager.
Server Port
Server port used by the multicast pipe manager. Will need to be configured the same
as the port on the client (for example, SCADA or DCS).
Multicast Group IP
Address
Broadcast address used when communicating to all other multicast devices. This
address will need to be the same on all communicating multicast devices.
Multicast Group Port
Multicast port used when communicating to all other multicast devices. This will need
to be the same on all communicating multicast devices.
3.14 Digital Input/Output
The functionality of the shared Digital Input/Output pin may be configured via the Transfer webpage. As this pin is
shared, the digital input status will be On when the digital output is set to On.
The Digital I/O channel can be transferred to/from another device using Modbus (see “3.15 Modbus I/O Transfer”
below) or it can be configured to provide status of the module communications. If the 245U-E disassociates from
another unit (that is, there is no wireless link), you can configure the digital output to turn On (set) or Off (drop).
Figure 44 Digital I/O
3.15 Modbus I/O Transfer
The 245U-E provides Modbus TCP client and Modbus TCP server functionality for I/O transfer. The 5000 x 16-bit
general purpose registers are provided for Modbus (including the onboard digital input/output) and are shared
for both client and server. Modbus TCP client (master) and Modbus TCP server (slave) are both supported
simultaneously, and when combined with the built-in Modbus TCP to RTU gateway, the 245U-E can transfer I/O to
and from almost any combination of Modbus TCP or RTU devices.
