Function Block values and Output status can be manipulated from the

Monitor option. When placed in the Run mode, the Alpha2 defaults

back to the I/O status screen. Press the “ESC and OK” keys together

to enter the Top Menu and then enter Monitor. The program will now be

displayed on-screen.

7.8.1 Monitor/Update Function Block Values

• Move to the function block to monitor and enter Setup FB. The

Function Block Values can be updated and monitored.

• Changes to current values will be valid only while in Monitor Mode.

• Changes to Set point data and the comparison values will be written

to the system memory.

7.8.2 Forcing Outputs ON/OFF

the program. To force an Output On, proceed to the Output name

and number and press the “OK” key. A solid rectangle will appear

underneath the block number to signify that the block is ON. Input pins

will have a smaller solid block next to their arrow to show that they are

activated.
