Technical data of product parameters

As an example, the transfer of 125680-01coils to a Slave may be performed using code 05 or code
15.
Using code 05, 1000 messages are required. Each transaction requires 16 bytes, plus the
delay in either end in interpreting and preparing messages. Each transaction requires125680-01
bytes) x 11 = 176 bits. At 9600 bits/second, this takes 18.33 ms. If the delay is assumed to be
only 1 millisecond, 100 messages take an absolute minimum of 19.33 seconds. The practical
delays are likely to extend or even double this time. This configuration is also too large to 125680-01
program into a Communications Interface!
Using code 15, 512 coils may be set in one message. Assuming two messages of 500 coils are
used, the transaction takes (9 + 500/8) + 8 bytes x 2 messages x 11 = 1,760 bits. At 9600
bits/second, this takes 183.3 ms, plus the turnaround delay. It is possible to write this data
four or five times a second if both devices can process quickly. A faster data rate would also 125680-01
speed the communications link. The coils must however be configured in a contiguous block
(without gaps). It is good practice to plan a Modbus map to include blocks of contiguous
data with room for spares.
Some devices are not configured to respond to multiple write messages. If necessary,
splitting the Modbus communication across more than one port or more than one CI will
improve data rates and response times.
