166 APPLIC ATION BLO CKS
12.1.3 Logic levels
Logic inputs will recognise the value zero, (any units), as a logic lo w. All other numbers, including negative
numbers, wi ll be recognised as a logic high.
12.1.4 Activating blocks
In order to activate a block it is necessary to configure its G OT O windo w to a PIN other than 4 00)Block
disconnect. In the CONFIGURATION menu first enter the ENABLE GOT O, GETFRO M windo w and set it to
ENABLED. Then staying in the C ONFIGURATIO N menu proceed to BLOCK OP C ONFIG to find the appropriate
GO TO. After completing the connection return to the ENABLE G OTO, GETFRO M windo w and set it to
DISABLED.
12.1.4.1 Conflicting G OT O connections
When the EN ABLE GOTO, GETFRO M windo w is set it to DISABLED, the system will undertake an automatic
conflict check. If it has found that there are 2 or more G OT Os connected to the same PIN, it will issue the
alarm GO TO CO NFLICT.
Proceed to 13.14 CO NFLICT HELP MENU in CONFIGURA TION to find the number of conflicting GOT O
connections, and the target PIN that causes the conflict. One of the G OT O connections must be removed to
avoid the conflict.
This process is repeated until there are no conflicts.
Note that this tool is extremely helpful. Without it there is the possibility that user GOT O configuration errors
would cause multiple values to alternately appear at the conflict PIN resulting in unusual system behaviour.
12.1.4.2 Application blocks PIN table
The application blocks start at PIN 401 and continue up to approximately PIN 670. There is a complete
numeric PIN table for these in the separate application blocks manual.
