data (d) is applied to all 3 COMM ports simultaneously
and can be any value from 0 to 255
e.g. SETSYSTEM 1, 3
The PLC will wait 3 x 150ms = 450ms for a valid response
from the slave controller on all 3 serial ports.

Number of Com Retries
# of retries if NETCMD$, READMODBUS, WRITEMODBUS,
READMB2 or WRITEMB2 failed to get a valid response
from slave controller.

For Nano-10, FMD and F-series PLCs
SETSYSTEM 2, data affects the 4 COMM port individually
(COMM4 is Ethernet client connection) , where bit 0 & 1
for COMM1, bit 2 & 3 for COMM2 , bit 4&5 for COMM3
and bit 6&7 for COMM4. By default data is set to &HAA
(binary 10 10 10 10). This means 2 re-tries (a total of 3 tries)
for all 4 COMM ports.

Where dd = 00, 01, 10, or 11
(maximum = 3 re-try)
In order to change the number of retries for COMM2 to 1
retry you have to set the bit 2 & 3 of data.
E.g
SETSYSTEM 2, &HA5
'binary 10 10 01 10
The above example set COMM2 to 1 retry and the other
3 ports are 2 retries.
