Details for DDEntity "170 - Actual Condensed Work State (145-160)"

170 - Actual Condensed Work State (145-160) Request changes
DefinitionCombination of the actual work states of individual sections or units (e.g. nozzles) number 145 to 160 into a single actual work state of their parent device element. The actual condensed work state contains the child element actual work states, in the driving direction from left to right, where the leftmost child element actual work state are the 2 lowest significant bits of the Process Data Value. Each child device elements actual work state is represented by 2 bits and defined as: 00 = disabled/off, 01 = enabled/on, 10 = error indicator, 11 = undefined/not installed. In total 16 child device element actual work states can be contained in one actual condensed work state of their parent device element. If less than 16 child device element actual work states are available, then the unused bits shall be set to value 11 (not installed). When the parent device element contains the Actual Condensed Work State DDE, then the device descriptor shall not contain the individual actual work state DDEs of the child device elements.
CommentSee the DDI 161 attachment "ISO11783-11-DDI-289-SetpointWorkState" for implementation guidelines. This DDE is used to reduce number of messages. Individual work state messages for a many-sectioned device can potentially cause performance issues due to overloading communication. With this DDE, 16 work states can be sent via a single message, resulting in less traffic to convey on/off status for an entire device.
