If the circulator is put into remote control mode via the
configuration level, the display will read
"r OFF" = REMOTE STOP.
The circulator is now operated via the computer.
In general, the computer (master) sends commands to the
circulator (slave). The circulator sends data (including error
messages) only when the computer sends a query.
After a power interruption in case of remote control the order to
start and all values which have to be adjusted, must be resent via
the interface from the personal computer.
AUTOSTART is not possible.
A transfer sequence consists of:
• address (RS485 interface only)
• command
• space (
⇔,
Hex: 20)
• parameter (the character separating decimals in a group is the
period)
• end of file (↵; Hex: 0D)
The commands are divided into in and out commands.
• in commands: asking for parameters to be displayed
• out commands: setting parameters
The out commands are valid only in remote control mode.
When the RS485 interface is used, the three-digit instrument
address stands in front of each command.
(example: address Ad32 = A032)
Examples:
Command to set the working temperature T1 to 55.5 °C:
out_sp_00
⇔
55.5↵
A032_out_sp_00
⇔
55.5↵
Command to ask for the working temperature T1:
in_sp_00↵
A032_in_sp_00↵
Response from the circulator:
55.5↵
A032_55.5↵
