Parameter Setting Display
This function is used to set the parameters of the main unit. There are setup parameters for setting the basic functions of a main unit controller and operation parameters used for setting functions necessary to operate the main unit. It is also possible to set them using the Setting wizard.
Proper management of the setting file minimizes the downtime during maintenance and inspection.
Program pattern setting function
This function is used to set the program pattern of the UP55A/UP52A
With the PC connected to one controller, the tuning function tunes PID parameters by displaying PV input values (PV), target setpoints (SP), control output values (OUT), etc. on the PC screen. Furthermore, it also enables the PV, SP, and OUT values to be displayed as trend data and acquired together with the loop information and fixed registers in the Tuning window. Acquired trend data can be saved in a file of .csv format.
The register monitoring function enables the main unit’s registers to be monitored and/or changed during ladder program debugging.
This function downloads parameter data, program pattern data and/or ladder program data to the main unit, uploads it from the main unit, and compares it with the main unit data. You can specify all data, or individual data items, to be uploaded or downloaded.
File management/print function
This function enables you to save created parameter data, program pattern data and/or ladder program data in a file. It also allows data to be printed out for submission to the customer.
Ladder program building function
In ladder programs, there are various computations for input and output signals, and sequence processing can be built using four fundamental arithmetic operations, logical operation, temperature compensation factor calculation, and pressure compensation factor calculation and between input and output contacts. A ladder program consists of three parts: the input ladder calculation executed before control computation, and the output ladder calculation and the user ladder calculation performed after control computation. Each calculation section is respectively executed every control period.
The sequence of calculation is: input, input ladder calculation, control computation, output ladder calculation, user ladder calculation, and output.
Building a ladder program
A ladder program is built by editing the default ladder programs provided for each control mode of system data. It is recommended that the user ladder calculation section be used if a sequence is 2 desired to be configured regardless of controller control computation. As the initial status, the default ladder programs are described in the input ladder calculation and output ladder calculation sections on a control mode basis. No program is written in the user ladder calculation section.
