custom function (trilogy 6)

[jackson5]

I don't understand how to get the custom function to influence relays and inputs.

I want to set up a custom function that would turn on a switch if certain conditions were met, but I can't work out how.

Thanks

Hello,

In the customs functions you have some TBASIC functions

SETIO relay/output-name           ' To set On the corresponding relay
CLRIO relay.output-name            ' To set Off the corresponding relay
TOGGLEIO relay/output-name     'To invert the current state of the corresponding relay (From ON to OFF  or OFF to On)

TESTIO (relay/output-name)      'To verify in an IF Statement.  function return 1 if the corresponding relay is ON and 0 if Off.

exemple:

IF TESTIO (RELAY1) = 0 THEN SETIO RELAY1 ENDIF         'Change the state of RELAY1 from 0 to 1

IF TESTIO (RELAY1) = 0 THEN TOGGLEIO RELAY1 ENDIF  'Change the state of RELAY1 from 0 to 1

In the I)Trilogy softwareinstallation you have a sample file that illustrate theses commands:

C:\TRILOGI\TL6\usr\Samples\setIO.PC6
