ICP DAS USA I-7540D - Manual (Page 100)

layer may respond with a “Disconnect” event to the VxComm Driver if it fails
to send the message after 20 seconds or more. Users can set a smaller
Connection-Broken time (for example: 10000 ms) to force the VxComm
Driver to re-connect again and get a quicker response.
If the connection has no sending/receiving signal before the
Connection-Broken time has timed out, the connection will be marked as
broken. The VxComm Driver will also re-connect it again. Thus, the
Keep-Alive Time should be smaller than the Connection-Broken time to
make the connection come on-line.
The default System Timeout (/STxxx) value of the i-7540D is about 300
seconds. After client programs have connected to the μPAC-7186E, clients
have to send command to keep the i-7540D alive before it times out,
otherwise the μPAC-7186E will reset itself and clients will have to reconnect
to the i-7540D again.
Users can set the Keep-Alive Time and Connection-Broken time to 0 to
disable this mechanism. The System Timeout will have to be set to 0 to
disable the reset mechanism.
z Connect Timeout (ms) field:
The timeout value will be passed into MS TCP/IP driver for reference when
connecting and disconnecting.
z Command TCP Port field:
By default setting, the i-7540D use TCP port 10000 as the Command /
Configuration port. If you change the setting of i-7540D, you must assign the
correct one in the field. So the VxComm Driver can connect to the right TCP
port.
This TCP port is used to configure the Baud rate, data format, CTS/RTS
control mode and Break, etc.
z Port7000 Port field:
By default setting, the i-7540D use TCP port 9999 as the Port7000 port. This
TCP port is reserved.
