Logging

Errors

Default = Selected. When selected, protocol and operation errors are logged.

Send messages

Default = Not selected. When selected, contents of poll request messages are displayed in the log viewer. The data logged will start with "S:" or "TX:"(in Hex by default).

Receive messages

Default = Not selected. When selected, contents of complete responses (including errors) are displayed in the log viewer. The data logged will start with "R:" or "RX:" (in Hex by default).

Device and item activity

Default = Not selected. When selected, ACM will generate the appropriate log message when items or devices are removed, added, activated, or deactivated.

Communication status changes

Default = Not selected. When selected, ACM will log whenever communication status changes from bad to good or vice-versa.

Data values received from device

Default = Not selected. When selected, an OPC item raw value, data type and quality will be logged after a poll that receives a good response or a poll that receives no response. The value will be in raw units (if it differs from the engineering units received from the OPC client).

Sample: “FATestLab, F8:1= 14.7 Q:0x00c00000 ID=100978032 VT=0x0004”

Data values sent to device

Default = Not selected. When selected, an OPC item value will be logged when an OPC client writes to an item, but before the write message is sent to the device. The value will be in raw units (if it differs from the engineering units received from the OPC client).

Sample: “FATestLab, F8:0Write Item = 14.5”

Data values written by clients

Default = Not selected. When selected, an OPC item value and data type will be logged when an OPC client writes to an item, but before the write message is sent to the device. The value logged will be in engineering units (if it differs from the raw units used when writing the value to the device).

Sample: “ACM, (Write) [DF1\FATestLab] F8:0= 14.5 ID=84447384 VT=0x0004”

Data values sent to clients

Default = Not selected. When selected, an OPC item data value, data type and quality will be logged after polling of such item is complete. This log is from host level. The value logged will be in engineering units (if it differs from the raw units used when writing the value to the device).

Sample: “ACM, [DF1\FATestLab] F8:0= 14.7 Q:0x00c00000 ID=84447384 VT=0x0004”

Configuration changes

Default = Not selected. When selected, ACM will produce a log entry indicating a change was made to the configuration.

Unsolicited messages from device

Default = Not selected. When selected, a message will be displayed when the device initiates a request to be polled (often called a report by exception).

Items in messages

Default = Not selected. When selected, a message will be displayed when OPC items are added or removed which changes the contents of poll request messages.

Warnings

Default = Not selected. When selected, a warning will be logged when ACM detects a potential problem, ACM may continue requested processes.

Suppress time sync detail

Default = Not selected. When selected, ACM will remove from the log viewer detailed messages pertaining to what is happening when a time sync occurs.

Footprint Level

None (Default).
Entry and Exit. Logs basic trace information between modules. This allows ACM support personnel to troubleshoot potential problems.
Entry, Exit, and Parameters. Logs trace information between modules, including parameters used in these functions.
