The delay period before transmitting each message after a socket connection request is sent (in milliseconds).

Some devices need a little bit of a buffer so they can “wake-up” and properly receive the request for data. For a weak 3G connection, 2000 or 4000 MS is suggested. However, also be aware that this delay precedes every message ACM sends on the port, so overall communication speed will decrease. |
Logging
Logging options:
- Errors. (Default = Selected) Any errors occurring with communications or with unexpected results.
- Send messages. (Default = Selected) Every message sent to a device to request data will be logged.
- Receive messages. (Default = Selected) Every message sent to a port to provide data will be logged.
- Device and item activity. When items or devices are removed, added, activated or deactivated, an appropriate log is generated.
- Communication status changes. A message will be logged whenever communication status changes from bad to good or vice-versa.
- Data values written by clients. When data is written to an item, it will be logged in logical units.
- Data values sent to clients. When data is received from the device, it will be logged in logical units.
- Configuration changes. A message will be logged when any change to the current configuration is made.
- Port usage. A message will be logged when a socket or serial port opens and closes.
- User actions. Logs protocol transactions and requests generated by user commands.
- Receive buffer changes. Logs each change to a port's data buffer due to data received from the port.
- Thread events. Logs polling thread state events such as open, transmit, user done, quiet and close.
- Trace interaction with protocol. Logs notifications between protocol and communication modules.
- Suppress write entries. Removes write transaction related messages from being logged.
