18
Cmd Count
This word contains the count of the number of
commands configured for the module.
19
Cmd Delay
This word contains the command delay counter preset.
There is a fixed delay between each command to
permit the module to perform other operations.
20
Cmd Queue
This word is set to zero if the command executing is
from the command list. If the executing command is
from the command queue, the word will be set to 1.
21
Cmd Queue
Count
This word contains the number of active commands in
the command queue for the module. Up to 100
commands can be buffered in this queue. These
commands are transferred from the processor to the
module using special command blocks.
22 to 23
Online Status
This double word value contains a bit for each of the 32
potential sessions in the module. If the bit is set for a
session in the double word, the station is online. If the
bit is clear, the station is offline. Use this value to
determine if commands sent from the processor will
have a chance of succeeding.
24
SNTP Valid
NTP time is valid (0=No, 1=Yes)
25
NTP Request
Number of requests to NTP server
26
NTP Response
Number of responses from NTP server
27
SNTP
Computation
Number of times SNTP time computed
28
SNTP Set
Number of times SNTP time set
29
NTP Timeout
Number of NTP response timeouts
5.3.3 Event Messages (9958)
Block 9958 is reserved to send event messages from the processor to the
module. Each block can send up to 10 events to the module. If a value of 9958 is
placed in the control register, event messages are sent from the processor to the
module. Refer to Events (page 156) for more information about timestamped
events.
The module supports a buffer queue of 99 events per data type. When the queue
is full, the module will delete the older event in the queue if a new event is
received.
This block should only be used to pass events with a predefined timestamp (the
module will also send timestamped events when database values change). While
using block 9958, disable the events for those specific points (refer to Group
Interrogation table) to avoid multiple event generation (caused by point value
update through the database).
The following table shows the block format for write.
