Supported device types and versions


The communication with the impulse power meters Incos/VUVT PM_EL 04 involves obtaining:

  • accumulated work for 3 tariffs
  • instantaneous power
  • quarter-hour power consumption, including the archival data

Communication line configuration


Communication station configuration


  • Communication protocol: Incos/VUVT PMEL 04.
  • A station address is a decimal number (or a hexadecimal number with a hash at the beginning, e.g. #0A) - according to the settings of PMEL configuration jumpers.
  • Time synchronization of the station is required.


Station protocol parameters

Communication station - configuration dialog box - tab "Protocol parameters".
They could influence some optional protocol parameters. You can set the following parameters:

Table 1

KeywordFull nameMeaningUnitDefault value
RC
Retry CountThe number of request retries when an error in communication occurs.-2
RT
Retry TimeoutThe delay between the retry call when an error in communication occurs.ms1000
WFT
Wait First TimeoutThe first timeout for response reading after sending the message.ms500
WT
Wait TimeoutTimeout between the response readings until it is completed.ms500
MWR
Max Wait RetryThe number of retries of response reading until it is completed.-8
SADDR
Source AddressCommunication address of the source (D2000 KOM).0 up to 254126
PMEL04B
PMEL04BCommunication with PMEL04B device.YES/NONO
TIMEST
TimestampPMEL04B with the support of timestamp transmission is used.YES/NONO
TMSYNC
Allow Automatic Time SynchroReal-time will be synchronized after the EM_TIM bit is set by a device (PMEL04B only).YES/NOYES

I/O tag configuration


  • I/O tags: Ai, Di, TiA, TiR.
  • I/O tag address is a decimal number in the range 0 up to 255 or a hexadecimal number with a hash at the beginning (e.g. #1A).
