Idx Variable Name / Brief Description Data Type Size StoreAccess /Usage /TransportDefault16 / 0BLOCK_OBJECTThis object contains the characteristics of the blocks.DS-32 20 Cst r / C / a –17 / 1ST_REVRevision counter for static variables. If a static variable changes its value, this counter isincremented by one.Unsigned 16 2 N r / C / a 018 / 2TAG_DESCEvery block can be assigned a textual TAG description.The TAG_DESC must be unambiguous and unique in the Fieldbus system.OctetString 32 S r,w / C / a ' '19 / 3STRATEGYThe STRATEGY parameter has a user-specified value. This assigned value can be usedin configuration or diagnostics as a key in sorting block information.Unsigned 16 2 S r,w / C / a 020 / 4ALERT_KEYThe ALERT_KEY parameter has a user-assigned value that can be used for sortingalarms or events generated by a block.Unsigned 8 1 S r,w / C / a 021 / 5TARGET_MODEThe TARGET_MODE indicates what mode of operation is required for the block. It isnormally set by a control application or by an operator through a human interfaceapplication. The input parameters are used by the algorithm in conjunction with the stateof the Function Block application containing the block to determine if the algorithm canachieve the target mode of operation established for it.See parameter 'MODE_BLK', 'Permitted' element for possible values.Unsigned 8 1 S r,w / C / a Auto22 / 6MODE_BLKThe MODE_BLK is a structured parameter composed of the actual mode, the normalmode and the permitted mode of the block.The actual mode is set (calculated) by the block during its execution to reflect the modeused during execution.Normal mode is the required operating mode of the block.The permitted mode shows which changes of the target mode are valid for the specificblock to the remote user of the MODE_BLK parameter.8: Auto16: Manual128: Out Of ServiceDS-37 3 D r / C / aActual:Out Of ServicePermitted:AutoManualOut Of ServiceNormal:Auto23 / 7ALARM_SUMThe ALARM_SUM parameter summarizes the status of up to 16 block alarms. For eachalarm, the current states, unacknowledged states, unreported states and disabled statesare maintained.DS-42 8 D r / C / a –24 / 8BATCHThe Batch parameter is necessary in a distributed Fieldbus system to identify used andavailable channels, in addition to identify the current batch in case of alerts.DS-67 10 S r,w / C / a –25 / 9UNUSEDUnused parameter.– – – – –26 / 10OUTThe Function Block parameter OUT contains the current measurement value in avendor-specific or configuration-adjusted engineering unit and the belonging state inAUTO MODE. The Function Block parameter OUT contains the value and status set byan operator in MAN MODE.101 5 D r,w / O / cyc –27 / 11PV_SCALEConversion of the Process Variable into percent using the high and low scale values. Theengineering unit of PV_SCALE high and low scale values are related directly to thePV_UNIT of the configured Transducer Block (configured via Channel parameter). ThePV_SCALE high and low scale values follow the changes of the PV_UNIT of the relatedTransducer Block automatically – a change of the Transducer Block PV_Unit causes nobump at OUT from AI.Float 8 S r,w / C / a –Table 2.7 Slot 5 – Analog Input 3 – Internal Volume Reverse Totalizer
