Programming the PFC with WAGO-I/O-PRO CAA
3.1.7.1 WAGO-I/O-PRO CAA library elements for ETHERNET
WAGO-I/O-PRO CAA offers various libraries for different IEC 61131-3 programming applications. They contain a host of modules that facilitate and speed up the creation of your application program. By default, the 'standard.lib' is included in a new project. The table below, described some of the other libraries that are available for ETHERNET projects with WAGO- I/O-PRO CAA.
|
standard. lib |
contains blocks for timers (TON, TOF etc.), triggers (F_TRIG |
|
|
|
etc.), string functions (LEFT, MID, LEN etc.), counters (CTD etc.) |
|
|
|
|
|
|
IECsfc.lib |
contains SFC functions that conform to the IEC standard |
|
|
|
|
|
|
Util.lib |
contains blocks for data manipulation, for example |
|
|
|
(HYSTERESIS, DERIVATIVE, INTEGRAL etc.), conversion |
|
|
|
(INT_TO_BCD etc.), control (PD, PID) |
|
|
|
|
|
|
Ethernet. lib |
contains blocks for communication over ETHERNET |
|
|
|
|
|
|
SysLibFile.lib |
contains functions that support a file system on the target computer |
|
|
|
|
|
|
SysLibVisu.lib |
defines structures for visualisation objects |
|
|
|
|
|
|
SysLibCallback.lib |
contains functions that serve to activate user-defined callback |
|
|
|
functions for runtime events |
|
|
|
|
|
|
SysRTC.lib |
contains functions for setting and reading the real-time clock on the |
|
|
|
CPU card and for interrogating a time server |
|
|
|
|
|
|
mod_com.lib |
contains functions for access operations to the process image |
|
|
|
|
|
|
SerComm.lib |
contains a function block for access to serial interface terminals |
|
|
|
and the configuration interface of the controller |
|
|
|
|
|
|
EML.lib |
contains functions that enable the controller as Ethernet-IP master |
|
|
|
to establish a UCMM connection to another node |
|
|
|
|
|
|
System.lib |
contains functions for runtime system diagnostics |
|
|
|
|
|
|
Modb_l05.lib |
contains function blocks that enable use of the controller via a |
|
|
|
serial interface module as a gateway to the MODBUS, which can |
|
|
|
have master or slave functions on the MODBUS |
|
|
|
|
|
|
ModbusEthernet_03.lib |
contains function blocks that serve to establish data exchange with |
|
|
|
several Modbus slaves |
|
|
|
|
|
|
Serial_Interface_01.lib |
contains a function block for transparent data transmission via the |
|
|
|
serial interface |
|
|
|
|
|
|
TerminalSlave_03.lib |
contains a function block for connecting external Modbus masters, |
|
|
|
such as text displays, terminals, control panels or graphic displays |
|
|
|
with Modbus_RTU protocol support |
|
|
|
|
|
|
Modem_01.lib |
contains function blocks for establishing and clearing a transparent |
|
|
|
modem connection. |
|
|
|
|
|
|
SMS_01.lib |
contains function blocks for sending SMS messages via a fixed |
|
|
|
network modem. The protocols UCP and TAP are implemented. |
|
|
|
|
|
|
GSM_SMS_01.lib |
contains a function block for sending and receiving SMS messages |
|
|
|
via a GSM modem and a block for parsing a string. |
|
|
|
By combining both blocks, a simple RPC interface can be realised |
|
|
|
in the controller. |
|
|
|
|
|
|
Mail_02.lib |
contains function blocks for sending e-mails |
|
|
|
|
