FAQ zu Multifunktionscontroller HE 5697 MFC


1. Can I retro­fit the MFC with a sec­ond card later?

For retro­fitting, it is rec­om­mended that the device is sent to the fac­tory, as this is the only way to main­tain the war­ranty and ensure per­fect func­tion­ing.

2. How large is the dis­play of the mul­ti­func­tion con­troller?

The dis­play of the MFC has a screen diag­o­nal of 3.5″ and a res­o­lu­tion of 320 × 240 pix­els QVGA.

3. Can I use my own graph­ics and images to cre­ate my Easy­Toll MFC projects?

Yes, you can import your own images such as but­tons, sym­bols or process images via the HMI para­me­ters in the “Screen” menu. A detailed expla­na­tion can be found in the Easy­Tool MFC oper­at­ing instruc­tions in chap­ter 6.5.2 on page 37.

4. Can I get an MFC from HESCH "pre­pared" for my appli­ca­tion?

The Easy­Tool MFC is designed so that every user can cre­ate their own appli­ca­tion.

5. What is the expected ser­vice life in oper­at­ing hours of the MFC dis­play?

The back­light­ing of the dis­play is reduced to 50% of the power after 20,000 oper­at­ing hours, but this is not an indi­ca­tion of the over­all ser­vice life of the dis­play.

6. What does the error mes­sage: "The cur­rent project does not match the device" mean?

Within an appli­ca­tion, it can hap­pen that blocks can­not be con­nected due to long lines or that the read­abil­ity of the appli­ca­tion is impaired. There are con­nec­tion blocks (data sources and data sinks) for this case. The required blocks can be found in the “Vari­ables” library and dif­fer accord­ing to data type (analog/digital) and source and sink.







The blocks can be placed, wired and renamed in the same way as stan­dard func­tion blocks. The fol­low­ing fig­ure shows an exam­ple of how the con­nec­tion is estab­lished with­out a direct con­nect­ing line with source and sink. The exam­ple is of course non­sen­si­cal, but is intended to illus­trate the prin­ci­ple of how a vari­able can be “trans­ported” with­out a con­nect­ing line.


The use of source and sink can be used both within an edi­tor win­dow and between any struc­ture blocks.

7. How can I change the order in which func­tion blocks are processed?

To change the order, the “Order” func­tion (menu ► Edit ► Order) must be acti­vated. The sequence is indi­cated by the num­ber­ing (num­ber high­lighted in orange).

The first sequence num­ber (block) that is dialed after acti­va­tion is assigned the num­ber one. Edit­ing the sequence can be ended by select­ing the “Sequence” func­tion again.

The sequence is defined sep­a­rately for the main edi­tor and all struc­tures. Of course, the struc­ture blocks are also given a num­ber for the sequence.

If the order is not spec­i­fied, the blocks are num­bered accord­ing to the order in which they are placed.

8. How can process data be logged in the device and then read or viewed from it again?

The LOGFILE, ALOGDATA and DLOGDATA func­tion blocks in the addi­tional func­tions library are avail­able to the user for data record­ing. These func­tion blocks are used to save data to the inter­nal mem­ory. The files can be down­loaded from the device via an FTP client for later analy­sis.

9. How many pro­gram steps can the pro­gram­mer exe­cute?

The pro­gram­mer can exe­cute 20 pro­grams, each with 60 seg­ments (pro­gram steps).

10. Where can I find the device dri­ver for the MFC and how do I install it?

The dri­ver is part of the Easy­Tool MFC soft­ware and can be found in the instal­la­tion path in the “rndis” folder.

The instal­la­tion of the dri­ver is described in the Easy­Tool MFC oper­at­ing instruc­tions.

11. Do you need the Smart­Con­trol soft­ware if you oper­ate HIMOD mod­ules in com­bi­na­tion with the MFC, or is the Easy­Tool MFC suf­fi­cient?

The Easy­Tool MFC can also inte­grate and para­me­ter­ize the HIMOD mod­ules. One excep­tion is the HIMOD Eth­er­net cou­pler – this requires its own IP address, which can only be set via Smart­Con­trol.
