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 line category: Serial, SerialOverUDP Device Redundant.
- Communication line parameters - according to the device settings.
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:
| 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) |
|---|---|---|---|---|---|---|
| 1 | 0 | 16 | 17 | 18 | 64 | 200 |
| 2 | 1 | 19 | 20 | 21 | 65 | 201 |

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.
