Identifier (serial number) of the flowmeter connected to the device. Electronic „seal” that is the check number of the measuring system. The program of TQI-021/1 generates this number automatically; there is no other way of setting it. In case any of the data in data group P is changed even temporarily, the check number will change. -

Batching suspended by a remote contact can also be terminated by the pushbutton ESC. MECHANICAL CONSTRUCTION TQI-021/1 is encapsulated in a standard size plastic enclosure that is to be built in by Figure 3.The front panel consists of a foil keypad and a graphic LCD display. The rear panel contains the terminals for connecting input and output cables. -

Page 17: Structure Of The Command Sent To The Device
TQI-021/1 4. Structure of the command sent to the device Address: Determines to which device the command is sent by the computer. The device interprets the command only if the value of item 051:Adr is equal to this byte. If the value of this byte is = 00H, the device executes the command independently of the value of 051:Adr. - Page 18 TQI-021/1 Info byte = item number STATUS byte: bit(7..4) = 0010B bit(3) = 1, if any of bits of item 000:Err is 1 bit(2) = 1, while batching is in progress bit(1) = 1, while zero calibration is in progress bit(0) = 0 byte is followed by info bytes depending on the received command.
- Page 19 TQI-021/1 - in case of relative type (150) item then bytes 7., 8. points to the number of the item storing the 0 % and 100 % value of the item, in case of other type of floating point data these two bytes do not give information for the user.
