Easy204DP slave to Fanuc Profibus Master
« am: April 30, 2004, 17:40:23 Nachmittag »
I am trying to interface an Easy800 with a 204DP profi-bus slave module to an Fanuc 30i with profi-bus master interface.  The Easy800 is functioning as a standalone PLC to control a hydraulics application.  The purpose of the 204DP unit is to hand shake 3 bytes in and 3 bytes out with the Fanuc 30i/Profi-bus master board.  I have read the GSD file (Moel4d10.gsd) and determined the communication settings, ID number, and module types for the Fanuc profi master, however, I am uncertain of the unique data that needs to be set under the Fanuc "slave user parameter" page.  I have my DI/DO registers, and slot parameters set, but the communication is still not working.  I believe this to be related to the "User Parameter" page. ???

Hi,

What are the versions of this two devices? You can find this code on the left side on the devices.

EASY800 04?? and EASY204DP 05??

The hardware that I have connected is as follows:

A.  EASY819-DC-RC (04-9044017302)
B.  EASY204-DP  (05-203500004831)
C.  EASY819-DC-RCX (04-9054005047)

I have logic that is up and running controlling a hydraulic system using the Easy 819 and the Easy 819-DC-RCX expansion module.  I need to handshake signals between this PLC setup and the Fanuc 30i CNC/PMC controller. 

I understand that my module types for the 3-byte I/O will be "92" and "A2" to exchange the data.

Hallo "kstenseth71,

The 3 byte modules defined in the GSD-File moel4d10.gsd are used to send the operands R1 to R16 from the PLC to the Easy800 (module 0xA2) and to receive the operands S1 to S8 from the Easy800 into the PLC (module 0x92). If you want to read/write other word operands like MD1 to MD96, it must be done using the 9 byte module (module 0xB8) from the GSD.

How to handle this is described in the "Operating manual EASY204-DP Profibus-DP Slave Interface, 05/03 AWB2528-1401GB" which is available at the Moeller FTP-Server. (URL: ftp://ftp.moeller.net/DOCUMENTATION/AWB_MANUALS/h1401g.pdf)

Chapter 4 (page 33ff) deals with the 3 byte modules for the R/S operands, while chapter 7, starting at page 79 gives you a detailed help with the 9 byte module.

For the 3 byte output module (module 0xA2, operands R1 to R16) you should set the first byte (byte 0, table 3 at page 35) to 0x10 or 0x20 according to the received value of byte 0 in the 3 byte input module (module 0x92) as described in table 1 at page 33 (with/without debounce). Don't use the Commands 0x30/0x40 and don't leave this byte at 0x00, that wouldn't work.

I'm not sure if this helps or if you already found out this information or may be given up in the meantime.

Sorry, I can't help you with the problem, how to handle your PLC Profibus master, because I do know nothing about the Fanuc PLC system.

Best regards

Bernhard

Der hat wohl eher durch einen Verdrahtungsfehler aus der easy einen Fluxkompensator gemacht.
