Figure 1: System Architecture—Modbus 250 Driver in RTU Master Mode (Firmware 2.x).

Notes on System Architecture

The Modbus 250 Driver in RTU Master Mode (Figure 1) with Firmware 2.

, supports

the following:

● Three physical FLNs (FLN 1 through FLN 3) on PXC Modular hardware, which

can be used for connecting and addressing either Modbus RTU or P1 devices on

RS-485 FLNs.

● Up to two physical FLNs (FLN 1 through FLN 2) on PXC-36 hardware, depending

on the ALN chosen, which can be used for connecting and addressing either

Modbus RTU or P1 devices on RS-485 FLNs.

Modbus 250 Driver on the PXC Series Platform Functionality ● ● ● ● ● Up to 95 virtual FLNs (6 through 100) for mapping devices accessed through Modbus RTU over Ethernet. Diagnostic Point 50 identiﬁes which FLNs are used for RTU communication (at and below the set value) and which FLNs are used for TCP communication (above the set value). Up to 247 device addresses per FLN. TX-I/O Modules. Maximum of 8,000 APOGEE points per driver. Maximum of 250 Modbus points per driver.
