networked Loop Control Unit via the
Node Terminal block
Note: The Controller Link Data Link
must be used.
Read/write of ITEMs in Loop Control Unit function blocks and execution of run/stop
commands are possible from the CPU Unit (including other networked nodes) or host
computer by issuing the following FINS commands to the Loop Control Unit.
- READ MULTIPLE ITEMS IN FUNCTION BLOCK (0240 HEX)
- WRITE MULTIPLE ITEMS IN FUNCTION BLOCK (0241 HEX)
- READ ITEM IN MULTIPLE FUNCTION BLOCKS (0242 HEX)
- WRITE ITEM IN MULTIPLE FUNCTION BLOCKS (0243 HEX)
- READ UNIT INFORMATION (0501 HEX)
- ECHOBACK TEST (0801 HEX)
- READ ERROR LOG (2102 HEX)
- CLEAR ERROR LOG (2103 HEX)
A Data Memory area comprising continuous 3836 words is used as communications I/O
area common to the Loop Control Units (3 units) on the PC.
System error 8 words x 3 units =
information 24 words
Area to send to 16 words x 32
computer blocks = 512 words
Area to send to all 2 words x 50 blocks
nodes = 100 words
Area to receive from 2 words x 50 blocks
all nodes x 32 nodes = 3200
words
Constantly ON flags, constantly OFF flags, clock pulse (ON/OFF every 0.5 and 1 seconds)
Differential output at 00:00 every day, noon every day, every 10 minutes, every minute and
every 10 seconds
Note: The CPU Unit's clock data are read as these clock data.
Year, year/month, month/hour, day/time, hour/minute and minute/second
Note: The CPU Unit's clock data is read as these clock data.
By front panel LED: unit number setting error, hardware test error, function block database
error, battery error
Storage of function block execution-related error codes to ITEM 003 of each function
block: source/destination designation error, illegal function block combination, illegal
parameter, etc.
