Bypass Status
Status Outputs configured for this function will indicate when an input is truly bypassed. A Safety Input is required to be determined
inactive at least once before a bypass can take place. The Status Output is active when the input is bypassed. A bypass cannot take
place (the input must be open) on power-up.
Track Input Fault
Status Outputs configured for this function will indicate any fault on an input.
OK to Cancel OFF-Delay
Status Outputs configured for this function will indicate when an OFF-delay can be cancelled — that is, when the cancel delay input can
be activated in order to keep the OFF-delayed Safety Output ON, or to immediately turn the Safety Output OFF.
4.9 Virtual Status Outputs
Using the PCI, the Safety Controller (model SC22-3E only) can configure up to 32 Virtual Status Outputs. These outputs can communi-
cate the same information as the Status Outputs (see section
4.8.1 Status Output Signal Conventions
on page 50), but over a network.
The Virtual Status Outputs appear and can be configured after the Enable Network Interface box is checked on the Network Settings
menu in section
on page 124.
One feature of the Virtual Status Outputs Properties window is the Auto Configure function. This function automatically configures the
Virtual Status Outputs to a set of commonly used functions, based on the current configuration. This function is best used after the config-
uration has been determined. After Auto Configure has been used, Virtual Status Output configuration can be manually revised.
The information available over the network is consistent with the logical state of the inputs and outputs within 100 ms for the Virtual
Status Output tables (viewable on the PCI) and within 1 second for the other tables (found on the included CD). The logical state of inputs
and outputs is determined after all internal debounce and testing is complete. The PC Interface network functions are covered in more
detail in the Ethernet Reference.
4.10 Commissioning Checkout
After power is connected to the Controller, the EDM has been properly configured, and the Safety Outputs have been connected to the
machine to be guarded, the operation of the Controller with the guarded machine must be verified before the combined system may be
put into service. To do this, a Qualified Person (see
Glossary
) must perform the commissioning checkout procedure; see section
Commissioning Checkout Procedure
on page 75.
