2.2 Architecture
The following diagram shows an example network that connects a Personal
Computer (PC) and a Modicon M340 or Quantum Programmable Automation
Controller (PAC) to a ProLinx 5204SE-MNET-PDPMV1 gateway.
You configure the gateway using ProSoft Configuration Builder (PCB) software
through an Ethernet connection. The gateway also uses its Ethernet port to
support the Modbus TCP/IP protocol, allowing it to communicate with the
Modicon processor, as well as other Modbus TCP/IP devices.
You can also use the Ethernet connection to manage your PROFIBUS network
slaves using ProSoft Technology Field Device Tool/Communications Device
Type Manager (FDT/comDTM) drivers for popular plant asset management
software, such as PACTware™ and Endress+Hauser FieldCare. For more
information on FDT/comDTM drivers for the gateway, please refer to the ProLinx
PDPMV1 Driver Manual, on the ProLinx Solutions CD-ROM.
The gateway's PROFIBUS port allows it to act as a PROFIBUS DP-V1 Master.
The special Application Communication Logic functions built into PCB create all
the Unity Pro Derived Data Types (DDTs), Variables, and Derived Function
Blocks (DFBs) needed by the Modicon processor to be able to send Modbus
TCP/IP messages and have those messages turned into PROFIBUS DP-V1
cyclic I/O and acyclic mailbox messages (called telegrams in the PROFIBUS
protocol). The gateway can also communicate with PROFIBUS PA slaves though
a third-party PROFIBUS DP-to-PA Link Coupler device (not supplied by ProSoft
Technology).
