Introduction
Standard IEC 61131-3 library
Documentation to standard ilbrary is on http://www.gebautomation.com/help/index.jsp?topic=%2Fcom.gebautomation.help%2Fhtml%2Ftech%2Fstdlib.html .
Functions and function blcoks from standard library works properly also in Simulator.
Metel IEC 61131-3 libraries
To show Metel libraries in IDE, must be select project device to "iplog_gama" and build it.
Only some functions and function blocks from Metel libraries will works in Simulator.
Asynchronous operations
Some long-time operations (reading from MODBUS) can not be done in one logic cycle.
To solve that, use all asynchronous function blocks in Metel libraries this general interface:
in | EXEC | bool r_edge | rising edge starts new operation | |
out | BUSY | bool | indicates that operation is pending | |
out | ERR | bool | indicates some error occurs | |
out | ERR_ID | word | identifies occured error by unique code | |
out | VALID | bool | indicates success operation and valid output |
