I/O Path A Link Status
This Bool variable will indicate any failure on the communications link between the
(2-Port)
selected Node Processor and Chassis Processors. If this variable is True, it
indicates normal communications of the I/O communications link, Comnnector J1 is
online.
I/O Path A Link Status
Bool variable will indicate any failure on the communications link between the
(4-Port)
This selected Node Processor and Chassis Processors. If this variable is True, it
indicates normal communications of the I/O communications link, Comnnector J3 is
online.
I/O PathB Link Status
This Bool variable will indicate any failure on the communications link between the
(2-Port)
selected Node Processor and Chassis Processors. If this variable is True, it
indicates normal communications of the I/O communications link, Comnnector J2 is
online.
I/O Path B Link Status
This Bool variable will indicate any failure on the communications link between the
(4-Port)
selected Node Processor and Chassis Processors. If this variable is True, it
indicates normal communications of the I/O communications link, Comnnector J4 is
online.
Scan Cycle
This integer variable indicates the time for one scan cycle in 100 microsecond
units. If the scan cycle is configured for 25 milliseconds, then the value of this
variable should indicate 250. The 3200T/3201 Processor includes a Windowed
Watchdog Timer (WWDT) with a minimum of 3 milliseconds and a maximum of 80
milliseconds. If the node processor deviates from this window, a board reset is
asserted
Scan Reserve
This integer variable indicates the idle time that the selected 3200T/3201
Processor has on each scan cycle. For example if the Scan Cycle is 50 and the
Scan Reserve is 30 for 3200T/3201 Processor A, then we can assume the
following: The 3200T/3201
Processor A’s overall cycle time is 5 milliseconds, it
completes all its scan and communications functions within 2 milliseconds, and has
3 milliseconds in reserve delay time. If reserve cycle time is not enough, then the
scan cycle should be re-configured.
I/O Comm. Error Count
This integer variable will count the number of invalid I/O communication messages
(detected by multiple CRC signatures on each message). If a Node Processor
does not receive a valid I/O communication message for three consecutive scan
cycles from any of the configured Chassis Processors and its redundant
processor(s) does, then the Node Processor will take itself offline.
Peer Comm. Error Count
This integer variable will count the number of invalid peer-to-peer communication
messages (detected by multiple CRC signatures on each message). If a
3200T/3201 Processor peer-to-peer message miss-compares for three consecutive
scan cycles then the Node Processor will take itself offline.
Host Comm. Activity Count
This integer variable will count the number of communications per scan cycle on
the host port (This includes peer-to-peer communications as well). If a 3200T/3201
Processor determines that there is too much activity, it will pause the host and
peer-to-peer communications and continue all other operations at the configured
scan rate. Therefore, this variable can point problems on the host network.
CPU Temp
This integer variable will hold the measurement of the 3200T/3201 Processor CPU
Temperature. A rise in temperature could indicate a fan failure; a temperature of
90º C or more indicates a critical error condition.
Board Temp
This integer variable will hold the measurement of the 3200T/3201 Processor
Board Temperature. A rise in temperature could indicate a fan failure; a
temperature of 90º C or more indicates a critical error condition.
