Modbus Gateway Settings

The scenarios in this section are used to illustrate how the IOLAN’s Modbus Gateway settings are

incorporated into a Modbus device enviro nment. Depending on how your Modbus Master or Slave

devices are distributed, the IOLAN can act as both a Slave and Master Gateway(s) on a multiport

IOLAN or as either a Slave or Master Gateway on a single port IOLAN.

Modbus Master Gateway

The IOLAN acts as a Master Gateway when the Modbus Master is connected to a serial port on the

IOLAN. Each Modbus Master can communicate to UIDs 1-247.

Modbus Slave Gateway

The IOLAN acts as a Slave Gateway when the Modbus Master resides on the TCP/Ethernet network

and the Modbus Slaves are connected to the serial ports on the IOLAN. Note: The IOLAN provides a

single gateway to the network-attached Modbus Masters. This means that all Modbus Slaves attached

to the IOLAN’s serial ports must have a unique UID. Multiple Masters on the network can

communicate with these Modbus Slaves. Not e : If a tran saction is in progress to a Modbus Slave,

other requests to that same device will be queued un til that transaction is complete.
