APPENDIX B - MODBUS MASTER CONFIGURATION
B-8
If no response is received from a slave all other messages that are currently
queued up for that slave address will be marked as no response and removed
from the queue. This will help wasting too much time on a slave device that is
no longer functioning.
If there are more than one of these EX blocks in the database the lowest
occurrence number EX block will be used.
INPUT8 INTER MESSAGE DELAY Local Long State
This parameter specifies the amount of time (in 50 ms units) that the driver
waits after a previous transaction has completed before sending another
message. Valid values are 0 through 255.
If there are more than one of these EX blocks in the database the lowest
occurrence number EX block will be used.
INPUT9 OUT OF RANGE VALUE READ Local Long State
This parameter specifies what should be done with an attribute’s value when
the register value that is read from a slave is out of the attribute’s data type
range. For instance a value of 300 was read and the data type is long state
which allows 0 through 255.
If there are more than one of these EX blocks in the database the lowest
occurrence number EX block will be used.
Valid values are 0, 1 or 2.
Value 0 indicates the input value should be left unchanged.
Value 1 indicates the input value should be set to minimum.
Value 2 indicates the input value should be set to maximum.
Data Type Minimum Value Maximum Value
DISCRETE 0 1
SHORT STATE 0 15
LONG STATE 0 255
DATE JAN 1, 1990 DEC 31, 2089
ASCII & HEX Significant Significant length set to field size - 1.
length set to 0 Extra bytes are truncated.
INPUT10 SINGLE WRITE FUNCTION CODE Local Long State
This parameter specifies which Modbus function code should be used when
writing 1 coil or register. Valid value are 0 and 1.
Value 0 indicates the Modbus code 5 (force single coil) or Modbus code 6
(preset single register) should be used.
Value 1 indicates the Modbus code 15 (force multiple coils) or Modbus code
16 (preset multiple registers) should be used.
If there are more than one of these EX blocks in the database the lowest
occurrence number EX block will be used.
