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 take-off, including the archival data

Communication line configuration

Communication station configuration

  • Communication protocol: Incos/VUVT PMEL 04.
  • A station address is a decimal number - according to the settings of PMEL configuration jumpers.
  • A time synchronization of 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

Key word Full name Meaning Unit Default value
RC Retry Count Number of call retries when an error in communication occurs. - 2
RT Retry Timeout Delay between the retry call when an error in communication occurs. ms 1000
WFT Wait First Timeout The first timeout for response reading after sending the message. ms 500
WT Wait Timeout Timeout between the response readings until it is completed. ms 500
MWR Max Wait Retry Number of retries of response reading until it is completed. - 8
SADDR Source Address Communication address of source (PC). 0 up to 254 126
PMEL04B PMEL04B Communication with PMEL04B device. YES/NO NO
TIMEST Timestamp There is used PMEL04B with the support of time stamp transmission. YES/NO NO
TMSYNC Allow Automatic Time Synchro Real time will be synchronized after the bit EM_TIM is set by a device (only PMEL04B). YES/NO YES

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.

Table 2: I/O tag addresses distribution:

Table 3: Di values, status bits (only PMEL04A):

Address Meaning
0 EPROM error.
1 RAM error.
5 Program restart on a process module.
6 Exceeding the time difference.
7 Acknowledgement of time settings.

Di values, digital inputs (only PMEL04B), addresses 0 up to 15.
