Operation Using a Programmable Logic Controller (PLC)
OUTPUT REGISTERS 01, 02, 03, and 04: Pump Status
The Pump Status registers contain a number that indicates the state of Pumps 1 — 4. This status can be used for general monitoring of the pump state, or as an indicator for driving independent pump operations. See INPUT REGISTER 02: Flush/Prime Pump Command, page 36.

OUTPUT REGISTER 05: Actual Mix Flow
The Actual Mix Flow register reports back the instantaneous mixing flow rate in cc/min.
NOTE: This register is valid only during a mix operation.
OUTPUT REGISTER 06: Actual Mix Ratio
The Actual Mix Ratio register contains the instantaneous calculated mix ratio.
•The value reported is the ratio antecedent multiplied by 100. The ratio consequent is always 1.
Example: Value = 250 >> A mix ratio of 2.5:1 (Material A to Material B)
•If the current recipe ratio is 0:1 (1K recipe) this value will be 0.
This register is valid only during a mix operation.
OUTPUT REGISTER 07: Actual Mix Potlife Remaining
The Actual Potlife Remaining register contains the current amount of time remaining in the active recipe’s potlife in seconds.
NOTE: If potlife is disabled for the active recipe or at initial startup this value will be 0xFFFFFFFF.
OUTPUT REGISTER 08: Active Recipe Number
The Active Recipe Number register contains the number of the active recipe (1 – 60).
•This value is 0 if the system was flushed.
•This value is 61 if the system does not know the current loaded recipe, if the recipe is invalid, or at initial startup.
OUTPUT REGISTER 09: Active Recipe Material A
The Active Recipe Material A register contains the number of the Color (1 – 30) that is associated with the current recipe.
•This value is 0 if the system was flushed.
•This value is 61 if the current recipe is invalid or at initial startup.
OUTPUT REGISTER 10: Active Recipe Material B
The Active Recipe Material B data register contains the number of the Catalyst (31 – 34) that is associated with the current recipe.
•This value is 0 if the system was flushed.
•This value is 61 if the current recipe is invalid or at initial startup.
•This value is 0 if the current recipe ratio is 0:1 (1K recipe).
OUTPUT REGISTER 11: Active Recipe Material A Flush Sequence
The Active Recipe Material A Flush Sequence register contains the number of the Flush Sequence (1 – 5) that is associated with the Color pump of the current recipe.
If the current recipe is invalid this value reflects the Flush Sequence associated with Material A pump of recipe 0.
