Recipe Buffers: DS – PLC Communication DS -> PLC 1. 2. 3. 4. 5. Header (Word): Initiates and drives the recipe activation Man. Reg Addresses (Word): Addresses of Manual Registers used in the recipe Man. Reg Values (Word): Manual Register values for addresses defined in 2) Request Addresses (Word): Addresses for the values used in the recipe Request Values (Float): Recipe values for the addresses defined in 4) PLC -> DS 1. Recipe Status (Word): Used by the PLC to acknowledge the recipe activation steps 17/03/2017 un. Recipe Component 7

Recipe Activation Sequence Win. CC OA Sent value = 1 PLC 1 – Send header buffer 2 – Copy header to status 3 – Send status buffer Rcp status = 1 Err Detail = 0 4 – Check status buffer 5 – Send recipe buffers (Man. Reg. Addr, Man. Reg. Val, Req. Addr, Req. Val) Sent value = 2 6 – Send header buffer 7 – Check Recipe ID 8 – Send status buffer Rcp status = 2 Err Detail = 0 9 – Check status buffer Sent value = 3 10 – Send header buffer (Activate recipe) 11 – Activate recipe 12 – Send status buffer Rcp status = 3 Err Detail = 0 13 – Check online values 17/03/2017 un.
