Introduction This document describes the use of the External Module option on the 5024G Weighing Ter- minal from Eilersen Electric. With the software version stated on the front page and with the External Module option enabled as well as a on RS485 externally connected communications module (MCE2035, 2070, MCE9637 or 2050) from Eilersen Electric the system can communi- cate with an external controller/PLC using Profibus-DP, PROFINET, DeviceNet or Ethernet-IP.
MCE9637 DeviceNet module, 2050 Ethernet module and 2070 PROFINET module. If no ex- ternal module is enabled the 5024G display will show “-------” / ”None”. Once a module type is enabled/selected the other settings (see descriptions below) are set to default values, which should normally be used.
Set/Read Bytes Out Number of bytes to be sent from the 5024G to the external module and from there to the Profibus-DP/PROFINET/DeviceNet/Ethernet master. This is the number of input bytes in the Profibus-DP/PROFINET/DeviceNet/Ethernet master. The value must be the same as the value in the external module. Normally this is 14.

Decimal point position indicates the number of digits after the decimal point in the display read- ing. It should be used to scale weight indications received/transmitted using the Profibus- DP/PROFINET/DeviceNet/Ethernet-IP communication. Load cell-Status[x] contains the actual status for load cell x. Load cell-Gross[x] contains the actual gross signal (not zeroed) on load cell x. WWW.EILERSEN.COM...
