Controller Password Protection
Beginning with controller firmware V06.00.00C, password protection can be applied as a security measure to restrict access
to the controller. The password has an eight-character limit and other requirements. For the instructions to set password
protection, change the password, and other details, refer to the
ToolboxST User Guide for Mark VIeS Functional Safety
Systems
(GEH-6862), the section
System Password Protection
for the component.

Shared IONet
The Shared IONet function (with ControlST V04.06 or higher) enables the sharing of Mark VIeS Safety inputs with another
basic process Mark VIe controller set, saving the cost of redundant sensors and I/O. Refer to the
Mark Controllers Shared
IONet User Guide
(GEH-6812) for more information.
2.4
Black Channel Safety Communication
Black Channel is a safety communications approach in which the new safety functionality is built over existing protocol
without impact to existing safety applications. The Black Channel feature provides the transfer of Safety control data between
two Mark VIeS Safety control devices without using the standard UDH network, providing a safer, less congested network. A
matching pair of transmitter and receiver blocks,
BLACK_TX
and
BLACK_RX
, are configured for the two Mark VIeS Safety
control devices in the application. The data is passed through Ethernet (similar to UDH EGD), and the BLACK_TX and
BLACK_RX blocks run a data integrity check on each respective side of the Black Channel. For more information on these
blocks, refer to the
Mark VIeS Safety Control Block Library
(GEI-100691), the chapters
Black Channel Transmitter (BLACK_
TX)
,
Black Channel Receiver (BLACK_RX)
, and
