ASCII Protocol

Transmission Sequence These commands are supported by the q.bloxx-modules with the TRION 35 CPU. All functions are tested with the APP-version greater "a04.95". Before this version the read and write variable value functions should be supported. There was a firmware failure so these functions did not work either.

Read variable value command with CRC

Start Addr Command Variable CRC End
Sign Module   Number   Sign
"#" "00".."15" "R" "00".."15" CRC "\r"

Read variable intermediate values with CRC

Start Addr Command Variable Selection CRC End
Sign Module   Number Subtype   Sign
"$" "00"..."15" "R" "00"..."15" "(0)"..."(4)" CRC "\r"

Subtype options (value of the corresponding signal-conditioning-function):

  • 0 ... netto-value (selnet() )
  • 1 ... tare-value
  • 2 ... brutto-value (selgro() )
  • 3 ... null-value
  • 4 ... raw-value (selunb() )

Read variable configuration with CRC

Start Addr Command Variable CRC End
Sign Module   Number   Sign
"#" "00".."15" "B" "00".."15" CRC "\r"
Start Addr Command Variable CRC End
Sign Module   Number   Sign
1 byte 2 bytes 1 byte 2 bytes 1 byte 1 byte

Read variable value without CRC

Start Addr Command Variable End
Sign Module   Number Sign
"$" "00".."15" "R" "00".."15" "\r"

Read variable intermediate values without CRC

Start Addr Command Variable Selection End
Sign Module   Number Subtype Sign
"$" "00".."15" "R" "00".."15" "(0)".."(4)" "\r"

Subtype options:

  • 0 ... netto-value
  • 1 ... tare-value
  • 2 ... brutto-value
  • 3 ... null-value
  • 4 ... raw-value

Read variable configuration without CRC

Start Addr Command Variable End
Sign Module   Number Sign
"$" "00".."15" "B" "00".."15" "\r"
Start Addr Command Variable CRC End
Sign Module   Number   Sign
1 byte 2 bytes 1 byte 2 bytes 1 byte 1 byte

The return value is a string of the addressed variable as a float number. The format is defined in the variable configuration.

Write Command with CRC

Start Addr Command Variable Value CRC End
Sign Module   Number     Sign
"#" "00".."15" "W" "00".."15" e.g. 1.0 CRC "\r"
Start Addr Command Variable Value CRC End
Sign Module   Number     Sign
1 byte 2 bytes 1 byte 2 bytes length of string 1 byte 1 byte

Write Command without CRC

Start Addr Command Variable Value End
Sign Module   Number   Sign
"$" "00".."15" "W" "00".."15" e.g. 2.0 "\r"
Start Addr Command Variable Value End
Sign Module   Number   Sign
1 byte 2 bytes 1 byte 2 bytes length of string 1 byte

The return value is a positive acknowledge 0x06 when the write was successful

  • the variable has an output part
  • the variable number exists

If the write access is not possible the return value is a negative acknowledge 0x15.

Examples:

 

Supported Baudrates

19200 bps
38400 bps
57600 bps
115200 bps
Additional Commands

The following commands can be used with or without the CRC

The determintation is done by the start sign "$"-without CRC and "#"-with CRC

Command without CRC

command with CRC

Start Addr Command CRC End
Sign Module     Sign

​The following 1 character commands are supported:

Command Description
"S" returns the location, serial-number and number-of-variables
"V" returns the Vendor-, Modul-name and the FPGA- OS- and APP-Version
"Z" returns the module error word 2-byte and the variable error word 4-bytes
"R" returns the results of all configured variables
