2 Description of the PC WORX SRT Software PLC
2.1 General description
The PC WORX SRT Software PLC is a PC hardware-based PLC with integrated PROFINET
and Modbus support. It can be used for simple automation tasks without hard realtime
requirements.
Supported hardware Valueline industrial PCs from Phoenix Contact (such as the VL BPC ..., see Section
“Ordering data” on page 68) offer optimum requirements for operating the Software PLC.
IEC 61131 control
performance
The PC WORX SRT Software PLC is consistently configured and programmed in
accordance with IEC 61131 using the PC Worx automation software. PC Worx can be
installed locally on the same PC as the Software PLC or on a separate PC. Programming in
all five IEC 61131 languages is supported.
The Software PLC can be used independently of the PC Worx software. For example, the
Software PLC and PC Worx can be installed on separate PCs. The Software PLC is
programmed via the network adapter which is assigned to the Software PLC. If the Software
PLC and PC Worx are installed on the same PC hardware, standard Windows mechanisms
are used for communication between these two applications, just like communication
between the Software PLC and the Windows operating system itself (see Figure 2-2 on
page 10).
Integrated Ethernet
functionality/PROFINET
The Software PLC can be assigned to one of the network adapters on the PC. It is used as
an external Ethernet interface. The Software PLC can be programmed via Ethernet with the
help of this interface.
When using the AX OPC server provided in the AUTOMATIONWORX Software Suite
Version 1.81 or later, the Software PLC data is available in the Ethernet network in a
standardized format and can be used for the different visualization packages.
In a PROFINET network, the Software PLC can be used as a PROFINET controller or
PROFINET device. As a PROFINET controller the Software PLC supports up to eight
PROFINET devices depending on the type of PC used.
For information on installing the PC Worx software, please refer to the quick start guide
for the software (see Section “Documentation” on page 69).
For additional information on PROFINET, please refer to the following documents (see
also Section “Documentation” on page 69):

Modbus functionality The Modbus TCP communication protocol can be used via the assigned network adapter
on the PC. In this case, the Software PLC can be used as a Modbus client. The Software
PLC can be used as a Modbus server with the aid of function blocks.
Local I/Os
(VL BPC MINI only)
Local digital I/Os which are integrated on the Valueline industrial PC (VL BPC MINI) are
supported by the Software PLC.
Status monitor of the
Software PLC
The status monitor of the Software PLC is displayed as an icon in the information area of the
Windows taskbar. The status monitor displays the operating states of the Software PLC
(see Section “Status monitor of the Software PLC” on page 32).
Ethernet interfaces of the
Software PLC
A network adapter on the PC is assigned to the Software PLC for operation. The Ethernet
adapter provides the Software PLC with an interface for external communication via
Ethernet. This interface is available to the Software PLC following installation and
assignment. In the example below, the PC has two Ethernet interfaces.
