Parameters –
Health Block
Once you have established communication with the controller, you may assign
parameters for I/O scanning.
Specify the starting register of the register block which will contain the health bits for
each of the I/O scanner transactions that you intend to configure.
If you designate a 3x register, the health bits for 64 transactions (maximum) will be
stored in 4 contiguous registers starting at the address you specify
If you designate a 1x register, the health bits will be stored in 64 contiguous discrete
registers.
A health bit is set only if the associated transaction has completed successfully
within the last health timeout period for that transaction. When the PLC is started, all
configured transactions have their respective health bit preset to 1. If the transaction
subsequently fails, then the health bit is cleared after the programmed health
timeout period has expired.
The health bits can be viewed by clicking on the PLC Status icon located in the
project tree.
