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 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.
- 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 |
|---|
| Retry Count | Number of call retries when an error in communication occurs. | - | 2 |
| Retry Timeout | Delay between the retry call when an error in communication occurs. | ms | 1000 |
| Wait First Timeout | The first timeout for response reading after sending the message. | ms | 500 |
| Wait Timeout | Timeout between the response readings until it is completed. | ms | 500 |
| Max Wait Retry | Number of retries of response reading until it is completed. | - | 8 |
| Source Address | Communication address of source (PC). | 0 up to 254 | 126 |
| PMEL04B | Communication with PMEL04B device. | YES/NO | NO |
| Timestamp | There is used PMEL04B with the support of time stamp transmission. | YES/NO | NO |
| 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 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).
Table 2: I/O tag addresses distribution:
| Electro meter | Instantaneous power (Ai) | Accumulation work tariff 1 (Ai) | Accumulation work tariff 2 (Ai) | Accumulation work tariff 3 (Ai) | Quarter-hour power take-off (Ai) | Time difference between curr. and prev. state (TiR) |
