So when we use RED_IN and RED_OUT?or F_1oo2AI?Can you refer me to a document about these functions? |

Hello, Look at SIMATIC Process Control System PCS 7 Compendium Part B - Process Safety and SIMATIC Process Control System PCS 7 Compendium Part A - Configuration Guidelines Best regards, Hristo Mihalev |

I didn't find anything about RED_IN/RED_OUT in these documents. |

Dear SM, where do you want to use RED_IN / RED_OUT? The driver-blocks do not have these parameters. Best regards, yy1 |

Hello all; I believe the original poster (SM) is refering to the function blocks FB 450 'RED_IN' and FB 451 'RED_OUT. as described below: Simatic Fault-tolerant systems S7-400H manual http://support.automation.siemens.com/WW/view/en/1186523 Ch. 10: Using I/Os in S7–400H 10.5 Connecting redundant I/O S7-400H134 System Manual, 02/2009, A5E00267695-06 "Functional I/O redundancy" block libraries The "Functional I/O redundancy" block libraries that support the redundant I/O each contain the following blocks: ● FC 450 "RED_INIT": Initialization function ● FC 451 "RED_DEPA": Initiate depassivation ● FB 450 "RED_IN": Function block for reading redundant inputs ● FB 451 "RED_OUT": Function block for controlling redundant outputs ● FB 452 "RED_DIAG": Function block for diagnostics of redundant I/O ● FB 453 "RED_STATUS": Function block for redundancy status information Configure the numbers of the management data blocks for the redundant I/O in HW Config "Properties CPU -> H Parameter". Assign free DB numbers to these data blocks. The data blocks are created by FC 450 "RED_INIT" during CPU startup. The default setting for the numbers of the management data blocks is 1 and 2. These data blocks are not the instance data blocks of FB 450 "RED_IN" or FB 451 "RED_OUT". You will find references to the different F-modules and the version of RED_IN and RED_OUT they can be used with, in the same chapter. For example: AI 6xTC 16Bit iso, 6ES7331-7PE10-0AB0 Notice: These modules must only be used with redundant encoders.You can use this module with Version 3.5 or higher of FB 450 "RED_IN" in the library "Redundant IO MGP" and Version 5.8 or higher of FB 450 "RED_IN" in the library "Redundant IO CGP" V50. This FB is available in STEP 7 V5.4.4 HF6 or higher. FB 450 can be used tpo find out the status of a redundantI/O module (passivation), amongst other things; FB 451 can be use to select a substitute value for a single redundant I/O channel when the corresponding parter is passivated 9instead of showing full value). Hope this helps, Daniel Chartier |
