48 Device Description
WAGO-I/O-PRO, which was expanded specifically with the target files for all
WAGO controllers.
The fieldbus controller has 1024 KB program memory, 512 KB data memory and
32 KB retentive memory available for the IEC 61131-3 programming.
Depending on configuration the user can access all fieldbus and I/O data.
In order to send process data via ETHERNET, the controller supports a series of
network protocols.
The MODBUS/TCP(UDP) protocol and the EtherNet/IP protocol are implemented
for exchanging process data. Both of these communication protocols can be
used either together or separately. For this, the write access to the I/O modules
(access via PFC, MODBUS/TCP or EtherNet/IP) is specified in an xml file.
For the management and diagnosis of the system, the HTTP, SNTP and SNMP
protocols are available.
For the data transfer via ETHERNET the FTP is available.
For the automatic assignment of the IP address in the network, kann alternatively
DHCP or BootP can be used.
The user can program clients and servers via an internal socket-API for all
transport protocols (TCP, UDP, etc.) with functional modules. Library functions
are available for function expansion.
With the IEC 61131-3 library "SysLibRTC.lib," for example, a buffered real-time
clock with date, time (1-second resolution), alarm functions and a timer is
incorporated. This clock is supplied with auxiliary power during a power failure.
This controller is based on a 32-bit CPU with multitasking capabilities, allowing
several programs to be executed in a near-simultaneous manner.
The controller has an internal server for the configuration and administration of
the system.
By default, the controller's built-in HTML pages contain information on the
configuration and status of the PFC, and can be read using a normal web
browser. In addition, a file system is implemented that allows you to store custom
HTML pages in the controller using FTP download or to store your own HTML
pages or call up programs directly.
