Non-Volatile Setup

These are integer (16 bit) types. Function code 3 reads, 16 writes. All allow read and write. Address range is 4801 to 4999.

This group of registers dictate certain system setup conditions. They are non-volatile.

4801 Read or write Reset non-volatile setup registers. Default value = 165. Writing a value other

than 165 to this register will cause the operating system to restore defaults to

registers 4801-4827. Restoration is performed on the next reset.

4802 Read or write Clear non-volatile integer and floating point registers. Default value = 165.

Writing a value other than 165 to this register will cause the operating system

to write 0's to all non-volatile integer and floating point registers. Reset is

performed on the next reset.

4803-4809 Read or write Reserved, unused

4810 Read or write Define COM3 port operation as ASCII or modbus mode.

0 = ASCII mode

1 = modbus mode (default)

4811 Read or write Modbus ID (0-255)

Default = 11

Current software will allow a 16 bit slave ID but will only use the lower 8 bits

(0-255).

4812 Read or write Reserved, unused

4813 Read or write COM3 baud rate

2 = 2400

3 = 4800

4 = 9600

5 = 19200 (default)

6 = 38400

7 = 57600

4814 Read or write Reserved, unused

4815 Read or write Modbus COM3 timer timout. Register value X 10 milli-seconds.

200 = 2 seconds (default)

When a print #3 message is sent, master mode will wait the amount of time

set in this register for data to start being received. If the message is not

recieved in time, the OS writes an error code 254 to register 4783. If data

starts coming into the buffer before the timeout expires, this register is no

longer in effect. Another 50 milli-second (fixed time) timeout takes over.

4816-20 Read or write Reserved, unused

4821 Read or write Reserved, unused

4822 Read or write Reserved, unused

4823 Read or write Switched V+ power control.

0 = Switched 12V & 5V off (default)

1 = Switched 12V & 5V ON

1 2 ... 38 39 40 41 42 43 44
