What are the system requirements for using SIMATIC PCS 7 Industry Library?
What should you watch out for when changing the symbolic addresses of input/output modules?
Why are the inputs of the driver block in the CFC chart no longer interconnected after replacing a HART analog module?
How do you parameterize the PCS 7 APL channel driver so that the output process value is inverted?
How do you configure a Modbus slave using the "RCV_341" (FB 121) PCS 7 block?
Why do I get the signal "QBAD" on my "CH_AI" driver block?
How do you configure the "Sample_T" input?
Why is the module INT_P issuing invalid values at the output?
Why isn’t the CH_AI block not interconnected automatically with the option "Create module driver"?
How can I change the preset message class in standard blocks?
Can blocks from the CFC library for the S7-300 CPUs also be used in a program for an S7-400 CPU?
What is the meaning of the block input VALUE_QC of the CH_DI block?
Why is the simulated value not output on the CH_AI driver block and how can a value still be simulated?
When do you speak of a "self-regulating process" and when of a "non-self-regulating process"?
How do you do perform controller optimization with the PCS 7 PID tuner?
What is the meaning of the parameters "GAIN", "TN" and "TV" with the CTRL_PID block?
Why is there only half the expected current output from each of the analog output modules in the case of redundant modules?
How much memory is used by the SIMATIC PCS 7 V6.0 library blocks and templates in the PLC?
What do I have to take into account to avoid that the actual value overshoots when switching over from hand/track operation to automatic operation of the "CTRL_PID" with activated setpoint ramp?
How can additional message texts - only as event and OS range - be edited in a block that supports messages in SIMATIC PCS 7 V5.x?
When generating the module drivers, how can you clear the message "Necessary files are missing for block CH_AI. Please note that you must install exactly that version of the library from which this block was imported"?
Why does the CH_AI driver report the slave still to be defective (QBAD=1) after failure and return of a PROFIBUS DP slave (e.g. ET 200M)?
How do you interconnect an FM350-2 in PCS 7?
How can you clear the error message "Value BITVAL is not defined in file AL_CHN.xml / CH_DI." in the module driver log?
Why do I get the signal "QBAD" on my "CH_AI" driver block?
Part number:

Description
When I set "TC-IL" (thermo-element, internal linearization) as measuring type for the relevant analog input module, a "QBAD" signal is display on the driver block "CH_AI".
This measuring type is supported only with Hotfix 2 for PCS 7 V5.0 + SP2. You can order this hotfix free of charge in Entry ID 5934475.

Install the hotfix and copy the function FC275 manually into your program from the block library. This replaces the older driver (update date 16.11.1999) with the new driver (update date 16.10.2000). The measuring type "TC-IL" then functions with this new driver.

Warning:
Since you have to copy the driver manually into the project, the drive update is only valid for the current project. You have to repeat the copying of function FC275 for new or other projects.
