MINT – IO
REF NO: m25A/om/101
Issue No: 11
Serial communication:
There are two
com-ports
are available for serial communication as
redundancy support Modbus RTU master. User can use only one port at a
time i.e. While com port 1 is in working mode(Enable) then com port 2 will be
in disable mode and vice versa.
Baud rate
with the range from 9600 to 115200 can be configuring here.
Parity bit
for non parity 0, even parity 1 and for odd parity 2 can be configure.
Any one com-port should be configured at one instance. They work as
redundancy logic. This logic changes communication link to other port for
failure of one port.
TCP/IP Ethernet communication:
IP address, Mask and gateway are configured as per network comfort.
According to factory setting, IP address is:192.168.100.110
Port number
is by default considered as 502.
Further configuration:
Delay
(com) (ms): controls the time between the receiving of single
characters.
Timeout
(com) (ms): time out occur when slave do not respond the query
within this specified time. This time have to specify at this address (45030) in
millisecond.
Timeout detect value:
if slave fails to respond query before time-out, then
some value should be indicate that slave respond value. This value has to be
stored in this register address 45029.
Retry
(com): it is number of retry count that the query needs to be resend on
its failure.
Watch
(com) (ms): it is a specified time, after that master resend request to
the slave. It is much larger then timeout time. And it helps to reduce total
query sending time.
Scan time
(com): It scans data from the register address after completion of
scan time cycle
DHCP/Static
: the IP address to mINT CP can be allocated according to
DHCP.
Note:
Current Model Not Support DHCP. Only static IP supports.
Security and reset:
Masibus provides password protection for configure data and direct write.
This
password
is written in register address 45097
Using this password and assigning data 5555 to address 45099 can set
all
data to zero.
For
direct communication with the IOs
, values 0, 1 and 2 have to initialize
in register 45100 for disable direct communication, via Ethernet and via USB
respectively.
