The following messages are logged by one or more of the Protocol Emulators (PEs).

Unsolicited message received. ID !OW out of range.
Current limit is !OW.
Explanation: Error. An unsolicited message was received from a PLC, but the unsolicited ID (PLC-2 address) was too large for the DAS. By default, the largest value for the unsolicited ID is 127 (decimal). This value can be increased by creating and setting the parameter ILAN$ABX_MAX_UNSOL_ID. The name of the parameter is different for each PLC family.
User Action: Create and set the ILAN$ABX_MAX_UNSOL_ID parameter to be larger than the unsolicited ID received or change the PLC logic to use a different PLC-2 address. The device must be disabled and then reenabled to use the parameter.

Unsolicited message received. No matching phypoint found for ID !OW.
Explanation: Error. An unsolicited message was received from the PLC, but a physical point with a matching unsolicited ID was not found for this device.
User Action: Create a physical point with a matching ID and format for the data received from the PLC, or change the PLC logic to send an unsolicited message with the unsolicited ID and format of an existing physical point.

Phypoint unsolicited ID !OW - out of range.
Current limit is !OW.
Explanation: Error. A phypoint has been created, but the unsolicited ID (PLC-2 address) was too large for the DAS. By default, the largest value for the unsolicited ID is 127 (decimal). This value can be increased by creating and setting the parameter ILAN$ABX_MAX_UNSOL_ID. The name of the parameter is different for each PLC family. If the device is disabled when the phypoint is created, this message is logged when the device is enabled.
User Action: Create and set the ILAN$ABX_MAX_UNSOL_ID parameter to be larger than the unsolicited ID used or change the physical point to use a different PLC-2 address for the unsolicited ID. The device must be disabled and then reenabled to use the new parameter.

Phypoint unsolicited ID !OW - already defined.
Explanation: Error. A phypoint has been created, but the unsolicited ID (PLC-2 address) is already in use by another phypoint. Unsolicited IDs must be unique for this DAS.
User Action: Create the phypoint using a different unsolicited ID (PLC-2 address).

Attempt to download !AD file to !AD.
Explanation: Error. An attempt was made to download a file that was uploaded from a PLC with a different processor type. Only files with the same processor type as the PLC being downloaded to can be downloaded.
User Action: Download a file with a processor type that matches the type of the PLC being downloaded to.

PLC memory too small to fit the requested file.
PLC logic file memory = !UL, PLC memory = !UL.
Explanation: Error. The size of memory in the file being downloaded is greater than the size of memory in the PLC being downloaded to.
User Action: Download a file with a memory image that is less than or equal to the actual size of the memory in the PLC.

Requested download file is not a valid PLC logic file.
Explanation: Error. The file was missing header information that identified the file as a valid PLC logic file.
User Action: Download a file that is valid to be downloaded to this PLC.

Data table size mismatch, file = !UW, PLC = !UW.
Explanation: Error. When attempting to download to a PLC-2 where the interface module is a 1771-KA revision A or 1771-KG revision A, the data table sizes did not equal each other.
User Action: Download a compatible PLC-2 file to the PLC-2.

Requested download !AD file, processor type mismatch.
Explanation: Error. An attempt was made to download a file that was uploaded from a PLC-5 with a different processor type and the OVERRIDE qualifier was not specified.
User Action: Download a file with a processor type that matches the type of the PLC being downloaded to or use the OVERRIDE qualifer to download a compatible PLC logic file.

Downloading !AD file to !AD.
Explanation: Informational. A file with a different processor type is being downloaded to a PLC-5 processor.
User Action: None.
