External PLC Configuration: Auto-Server Mode (Default)
While in Auto-Server mode the # of scan lines and the actual scan lines themselves cannot be edited.
Auto-Server Mode looks at the other protocol and then configures the Scan Lines within the PLC to
match. The PLC Tag/File Names and Data Types will be defined after the other protocol is configured.
If the PLC is a CompactLogix, ControlLogix, or FlexLogix, the data will be configured according to the
following rules:
• Any 8 Bit Signed/Unsigned data will be mapped as Sint.
• Any 16 Bit Signed/Unsigned data will be mapped as Int.
• Any 32 Bit Signed/Unsigned data will be mapped as Dint.
• Any 32 Bit Float and 64 Bit Float data will be mapped as Real.
• Any Coils or 1 Bit Binary Packs will be mapped as Bool (1 Bit).
• Any Coils or 8/16/32 Bit Binary Packs will be mapped as Bit Array (32 bit).
• Any String Data Types will be mapped as String.
If the PLC is a MicroLogix, SLC, or PLC5E, the data will be configured according to the following rules:
• Any 8 Bit Signed/Unsigned and 16 Bit Signed/Unsigned data will be mapped as Int.
• Any 32 Bit Signed/Unsigned, 32 Bit Float, and 64 Bit Float data will be mapped as Real.
• Any Coils or 1/8/16/32 Bit Binary Packs will be mapped as Bit Array (16 bit).
• Any String Data Types will be mapped as String.
Regardless of PLC type, the following is also true:
• The Read or Write direction depends on whether it is configured as a Read or Write on the other
protocol.
• If the other protocol exceeds the number of Sint, Int, Dint, Real, Bool, Bit Array, or String Data
Types the Allen-Bradley PLC supports (see limits on webpage), then nothing will be mapped. You
will see the # of Scan Lines remain at 0 and the main page will display the following error:
o To fix this error, simply decrease the amount of data you configured on the other
protocol so that the max number of Tag/File Name is not exceeded OR call customer
support to increase the limits.
