Page 69: I/O
3.3 I/O 3.3 I/O 3.3.1 Standard built-in I/O The LC53* has built-in I/Os by standard. Therefore, when standard built-in I/Os are used, no additional I/O module needs to be registered. I/O data can be input or output with I/O variables (SIO). The table below shows the description of the standard built-in I/Os.
Page 70: Standard I/O
Chapter 3 Software Functions 3.4 Standard I/O 3.4.1 Tags and standard I/O functions The relations between tags, standard I/Os, and programs are described below. Standard I/O functions consist of PV process, LP process, and PB process. Assuming general process control, the external sensor signal is input to the PV process as a feedback value first.
Page 71: Standard I/O Process
3.4 Standard I/O 3.4.3 Standard I/O process The standard I/O processes perform correction calculation, conversion process, and alarm process for the I/O data of the I/O module according to the parameters of the tag variables. The standard I/O process for different types of tags are described below.
Page 72 Chapter 3 Software Functions ■ Pulse instantaneous value conversion For pulse instantaneous values, only input from the intelligent serial PI module is used. The following instantaneous value calculation is performed. (Instantaneous Value) = [(Pulse Difference Count) X PU X D X K X T] /(Scan Time) Similarly to the analog instantaneous value, correction can be made in the application.
Page 73 3.4 Standard I/O (2) LP process The following processes are performed according to the controller (parameter) settings. ■ Current output conversion When Control Mode = For C, A, or RM, MV is converted to the output counter of intelligent serial AO.
