ModWeigh Design Codes Code Description

1 - 127 standard ASCII characters 128 - 191 reserved

Register Instructions 192 NOP no operation 193 RECALL register register is an ASCII Modbus address (8000 to 8992). It may take the form PpSsRrrrr where p is the port number,

s is the slave address and rrrr is the Modbus register. e.g. P2S3R8074 retrieves data on COM2, slave address 3 at register 8074. If either the port or slave_address are not specified, the values in the port and slave_address registers are used (see RECALL ).

b is the count by. Any one or combination of the three parts can be included. (e.g. C10d2b5 sets the column width to 10, the decimal places to 2 and the count by to 5; C10 sets column width to 10). The default is 0.

213 NEWLINE 214 NEWPAGE 215 TAB is a number 1 to 99. Columns are numbered from 0. 218 LIST is number 1 to 99. If = 101, lists design number in VALUE. 219 DUMP is number 1 to 99. If = 101, lists design number in VALUE.

Calculation Instructions 220 VALUE number number is an ASCII number (e.g. 123.4) If there

is no number, then the stack is pushed up. 221 ADD VALUE = VALUE + Y 222 SUB VALUE = VALUE + Y 223 MUL VALUE = VALUE + Y 224 DIV VALUE = VALUE + Y 225 MOD VALUE = VALUE + Y 226 SWAP_VALUE_Y VALUE and Y swapped 227 ROLL stack rolled down 230 CLEAR_VALUE VALUE is set to zero 231 CLEAR_ALL VALUE, Y, Z and T all set to 0 232 INC_ VALUE VALUE = VALUE + 1

Calculations are done on a stack in RPN (reverse polish notation). When a value is entered onto the stack with a RECALL or VALUE instruction, the other values on the stack are moved up first. An instruction like ADD or MUL operates on the values in VALUE and Y and places the result in VALUE. Z is moved to Y and T is copied to Z. The operation follows the values. e.g RECALL VALUE 2 MUL., this multiplies the weight by 2. e.g. 2 + 3 x weight = VALUE 2 VALUE 3 RECALL MUL ADD

233 DEC_ VALUE VALUE = VALUE 1

235 CHANGE_SIGN sign of VALUE changed, plus and minus

ROLL ADD, SUB, MUL, DIV, MOD

236 ABS absolute value of VALUE T T lost / copied 237 INT integer value of VALUE (e.g. INT(12.54) = 12) Z 238 FIX fixed value of VALUE (e.g. INT(12.54) = 13) Y

VALUE 0 RESULT

Looping and Control Instructions 240 IF is a logical expression made up of one or more values and operators evaluated from left

to right. e.g. IN3 OR NOT IN4 = value [NOT] [operator] [value] [NOT] [operator] NOT reverses the sense of the value, (e.g. true becomes false).

To Adjust A Setting Press the EDIT key to allow changes to the selected setting. If editing is locked, a password will be requested. For Quick setup and Main setup, the password is 111. For Service setup the password is 9713. For Altered setup there is no password as settings are display only.

Use the keypad and/or UP and DOWN arrow keys to increase or decrease the displayed setting. Some settings allow only one method, and some are display only.

Holding either key down will automatically continually increase or decrease the value.

Alarms An alarm is indicated by the light above the ALARM key flashing. An alarm number will flash in the display while a fault is active or until it is acknowledged. 30

Press the ALARM key to see the Alarms menu and acknowledge the alarms. The menu shows a list of the previous alarms.

For details on an alarm in the list, use the UP, DOWN and ENTER keys, or key in the number next to the alarm.

Press BACK to exit the Alarms menu, or press 6 to clear the alarms and exit the menu.

Modbus Access The Modbus protocol supported is RTU. (ASCII mode is not supported). Transmission is with 8 data bits, no parity and 2 stop bits. The following function codes are supported;

3 - read holding registers

4 - read input registers

6 - preset single register

16 - preset multiple registers (10 hex)

23 - read/write multiple registers (17 hex)

Data can be accessed as floats (4 bytes) or integers (2 or 4 bytes). Floats are preferred as the data is stored in engineering units. The following table shows how the addresses shown in the setup sum-mary are translated into Modbus register addresses. (Note with Modbus protocol, the actual address transmitted is one less than the register address. With some systems, you must specify an address one less than expected).

The interface registers starting at address 8000 contain the most common data required for Modbus access.

Modbus registers are 2 bytes, so 4 byte floats or 4 byte integers are stored in two consecutive regis-ters.

The following tables provide information for Modbus access to the transmitter. Address Data description

1000 to 4999 Design strings (contains printouts and programs) 8000 to 8029 Interface registers (PLC access) 8030 to 8699 Configuration settings (full instrument calibration) 8700 to 8899 Data outputs (values produced by the instrument) 8900 to 8999 Activations (when set, a process is activated)
