hi,
I'm trying to read data from a device.
Protocol is modbus TCP and I connected it to Ethernet. It supports SCADA TCP interface.
I'm using modpoll master simulator from my computer. But I get a response "Can't reach server/slave! Check TCP/IP and firewall settings" again.
Response is below.
..............
~~~>modpoll -mtcp -r1 -c10 -1 10.180.121.114
modpoll 3.6 - FieldTalk(tm) Modbus(R) Master Simulator

Protocol configuration: MODBUS/TCP
Slave configuration...: address = 1, start reference = 1, count = 10
Communication.........: 10.180.121.114, port 502, t/o 1.00 s, poll rate 1000 ms
Data type.............: 16-bit register, output (holding) register table
Can't reach server/slave! Check TCP/IP and firewall settings.

Both my computer and the device are in same network, and I can ping it by IP and status is fine.
Also I set modbus slave simulator at another computer and tested. It was successful.
I can't figure it out what is going on.
Plz let me know how.
Thanks.
