For CTR/PTR ratio “write multiple registers’ code is used. Since PTR/CTR primary & secondary value are of 2 word long , while write holding register can send only one byte of data at a time so because of this write multiple register code is used to send both 2 word together. Here in code we have sent both primary & secondary value of CTR/PTR together. This is done so that the ratio can be computed immediately and error can be flagged if ratio is invalid. If primary and secondary are sent independently, ratio computation may not be correct with new value of one parameter and old value of another. The ratio of CTR/PTR is calculated from the primary & secondary value, & depending upon that if the ratio is within the maximum limit than the primary & secondary values are stored in memory otherwise no change in the output takes place. Example:

Consider that if we want to set PTR ratio as 1000 for that we have consider PTR primary value as 1000 & PTR secondary value as 1. So the data that will be sent through modbus is given below 01 10 00 FC 00 04 08 03 E8 00 00 00 01 00 00:


22

Here 01 is the slave address, 10 is the function code, 00 FC is the PTR primary address. 00 04 is the quantity of register, 08 is the no. of byte, 03 e8 00 00 is the value for PTR primary i.e. is 1000 & 00 01 00 00 is the value for PTR secondary i.e. is 1. Exception code logic:

If incorrect function code : Exception code = 01 If registers requested not in range 0 – 32 : Exception code = 03 If requested addresses invalid : Exception code = 02 If Slave internal error : Exception code = 04

The limits checks are provided by first comparing the address of the incoming message with the assigned address for the various parameters in order to know that message belongs to particular parameter. Now the value in the message is compared with the boundary limits of that particular parameter & if the value is out of the boundary range then exception value [03 = illegal data value] is

Since Logged data will be larger than 125 bytes, master would send multiple read requests, in order to read complete logging data.

It is unknown to the master before hand as to how many data bytes are logged in memory; hence the master would be required to send the read requests until it receives an exception saying invalid address, which would indicate that all logged data has been read.

In case of error in communication at any point during logged data transfer, master may initiate the read from the beginning or from the address where the communication had failed.

Since protocol allows only 64 K of memory addressing, the total available memory is divided into 4 pages, numbered 0 – 3. Hence master has to update the page register in order to read form specific page.

It is not possible to read from addresses 0x00 to 0x399 when page register 0 is selected (Reserved for configuration data can be read by selecting Page number 4 as mentioned above). Master will get an exception Invalid Address in case an attempt to read this space is made for page register 0.

Only 64 bytes of data can be read per message as opposed to 125 defined by the protocol, in order to maintain proper page boundaries. Once data from one page is read, Master must ensure incrementing the value of page register in order to read


27

further data. Table below give information about page number and valid address range.

Page Number Start Add End Add0 0x0400 0xFFFF1 0x0000 0xFFFF2 0x0008 0xFFFF3 0x0000 0xFFFF4 0x0000 0x0399

The protocol for log data is given below

<0xABAB (16 bit)> <Number of data byte (16 bit)><Actual Data byte (number of data byte)><CRC (16 bit)>

In this 0xABAB is header which indicate start of data log frame, next two bytes are give number of data bytes log in log period. After that actual parameter are log. At end of each frame of data logging 16 bit CRC for error check.
