Note
Errors generated by FAL(006) can be cleared by executing FAL(006) with FAL
number 00 or performing the error read/clear operation from the CX-Program-
mer.
When input condition B goes ON, an error with FALS number 3 is generated
and A401.06 (FALS Error Flag) is turned ON. Program execution is stopped.
Errors generated by FALS(007) can be cleared by eliminating the cause of the
error and performing the error read/clear operation from the CX-Programmer.
When the CX-Programmer Ver. 6.11 (and later versions) is used, frequently
used processes can be encapsulated as function blocks (FBs). Function
blocks allow complex programming units to be reused easily, with the I/O data
treated as just a user interface to external applications.
The function block’s internal programming can be written in either ladder pro-
gramming language or in the structured text (ST) language. With ST lan-
guage, it is easy to program mathematical processes that would be difficult to
enter with ladder programming.
OMRON function blocks conform to the IEC 61131-3 function block standard.
The IEC 61131 standard was defined by the International Electrotechnical
Commission (IEC) as an international programmable logic controller (PLC)
standard. The standard is divided into 7 parts. Specifications related to PLC
programming are defined in Part 3 Textual Languages (IEC 61131-3).
The user can create function blocks in the CX-Programmer and place these
function blocks in regular programs. In addition, OMRON provides a library of
standard function blocks in its FQM1 Smart FB Library, which can be copied
and placed in regular programs. Function blocks have the following features:
• Function block algorithms can be written in the ladder programming lan-
