Question:<\/b><\/p>\n

Sometimes, the device’s I\/O point address is higher than 65535, which surpasses the 2-octet value supported by conventional parameterization (N <\/i>parameters). In this case, how can I parameterize the driver’s I\/O tags?<\/p>\n

Solution:<\/b><\/p>\n

To do so, you have to parameterize the driver’s I\/O tags via strings at ParamDevice <\/i>and ParamItem <\/i>fields. This parameterization was implemented at the driver to support addresses longer than 2 bytes that are required by a few devices.<\/p>\n

To parameterize tags via strings, you must first reset the N <\/i>parameters. Then place the PLC address at ParamDevice <\/i>field and the tag address at ParamItem<\/i>.<\/p>\n

The syntax at ParamItem <\/i>field for monitoring data is:
\n
\n:[]
\n<\/b>
\nWhere:<\/p>\n

<\/b>\u00a0 is the datatype’s mnemonic: SP, DP, ST, BO, MEn, MEs, MEf. The colon (:) separating the mnemonic from the object’s address is optional. The table below displays the monitoring datatypes and their mnemonic symbols:<\/p>\n

\"\"<\/div>\n


\n<\/b>is the tag’s address, which could be displayed in one of the following formats:<\/p>\n

\"\"<\/div>\n

<\/b> is an optional character that sets up the priority with which data is sent (in case of a slave driver):<\/p>\n

    \n
  • when the character is omitted, data is sent with default <\/b>priority (digital data with high priority, analog data with low priority; default priority can be configured at the driver’s settings)<\/li>\n
  • when the character is an exclamation point (!) , data is sent with high <\/b>priority. Example:\u00a0 SP:255!<\/li>\n
  • when the character is a less-than sign (<), data is only sent in the next general query. Example: SP:255<<\/li>\n
  • when the character is an equals sign (=), data is sent with low <\/b>priority . Example:\u00a0 SP:255=<\/li>\n<\/ul>\n

    The syntax at ParamItem <\/i>field for (master driver only) commands is:<\/p>\n

    :.[()]<\/b><\/p>\n

    Where:<\/p>\n

    \u00a0<\/b> is the datatype’s mnemonic: CBO, CBOt, DC, DCt, RC, RCt, SC, SCt, SEn, SEnt, SEs, SEst, SEf, SEft. The colon (:) separating the mnemonic from the object’s address is optional. The table below displays the monitoring datatypes and their mnemonic symbols:<\/p>\n

    \"\"<\/div>\n

    \u00a0<\/b> is the tag’s address, which could be displayed in one of the following formats:<\/p>\n

    \"\"<\/div>\n

    <\/b> is the command type, which could be:<\/p>\n

      \n
    • Select<\/b>: selects the command<\/li>\n
    • Execute<\/b>: executes the command<\/li>\n
    • Deactivate<\/b>: deactivates a previously sent selection<\/li>\n<\/ul>\n

      <\/b> is an optional parameter, to be informed between parenthesis. The available options are:<\/p>\n

        \n
      • (LongPulse)<\/b>: sends a long pulse<\/li>\n
      • (ShortPulse)<\/b>: sends a short pulse<\/li>\n
      • (PersistentOutput)<\/b>: generates an output with persistent value<\/li>\n
      • Omitted<\/b>: no qualifier specified<\/li>\n<\/ul>\n<\/div>\n
