Remarks
The following table describes host the NDM signal table is layed out into 4 seperate blocks specific to SLMP.
The SLMP "ControlBit" signal table/block organizes the single bit NDM signals sent from the PLC to Vision System. The ControlBit block is 80 bits long. +----------------+---------+-------+----------+-----------+-----------+------------+-----------+---------+ | | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 | +----------------+---------+-------+----------+-----------+-----------+------------+-----------+---------+ | 0 | Set | Clear | Rsvd | Initiate | Rsvd | Rsvd | Buffer | Trigger | | | Offline | Error | | Job | | | Results | Enable | | | | | | Load | | | Enable | | +--------------------------------------------------------------------------------------------------------+ | 1 | Rsvd | +--------------------------------------------------------------------------------------------------------+ | 2-5 | SoftEvent 0-31 | +--------------------------------------------------------------------------------------------------------+ | 6 | Rsvd | Rsvd | Rsvd | Rsvd | Set User | Clear | Inspection | Trigger | | | | | | | Data 0 | Exposure | Results | Camera | | | | | | | | Complete 0 | Ack 0 | 0 | +--------------------------------------------------------------------------------------------------------+ | 7 | Rsvd | Rsvd | Rsvd | Rsvd | Set User | Clear | Inspection | Trigger | | | | | | | Data 1 | Exposure | Results | Camera | | | | | | | | Complete 1 | Ack 1 | 1 | +--------------------------------------------------------------------------------------------------------+ | 8 | Rsvd | Rsvd | Rsvd | Rsvd | Set User | Clear | Inspection | Trigger | | | | | | | Data 2 | Exposure | Results | Camera | | | | | | | | Complete 2 | Ack 2 | 2 | +--------------------------------------------------------------------------------------------------------+ | 9 | Rsvd | Rsvd | Rsvd | Rsvd | Set User | Clear | Inspection | Trigger | | | | | | | Data 3 | Exposure | Results | Camera | | | | | | | | Complete 3 | Ack 3 | 3 | +--------------------------------------------------------------------------------------------------------+ The SLMP "StatusBit" signal table/block organizes the single bit NDM signals sent from the Vision System to the PLC.
