Simatic/TI 505 Ethernet Driver Help

Note: All 10 characters are displayed with the null-terminated string "hello" padded with 5 spaces to fill the 5

words.

To write "world" to this address, the memory data would look as follows:

V200/MSB = 'w'

V200/LSB = 'o'

V201/MSB = 'r'

V201/LSB = 'l'

V202/MSB = 'd'

V202/LSB = ' '

V203/MSB = ' '

V203/LSB = ' '

V204/MSB = ' '

V204/LSB = ' '

V205/MSB = ' '

Since "world" is less than 10 characters in length, it is padded with blanks to become 10 characters in length.

Packed Task Code Protocol

The following address types, strings, and arrays are not supported under Packed Task Code Protocol. To increase

efficiency, CAMP Protocol will be used instead.

Drum Count Preset (DCP)

Discrete Input (X)

Discrete Output (Y)

Discrete Control (C or CR)

Addresses greater than '30720' for Drum Step Preset (DSP) and Drum Step Current (DSC)

Notes:

1. Packed Task Code Protocol will be used for writing address types X, Y, and C.

2. If the TI565 option is selected in Communications Parameters, Packed Task Code Protocol will be used for

reading and writing the X, Y, and C address types independent of the 505 Protocol setting.

3. Task Codes TC7F (Read Block) and TC5A (Write Block) are used.

Status Words

For all Status Words, Bit 1 is the Most Significant Bit (MSB) and Bit 16 is the Least Significant Bit (LSB) in order

from left to right. Users can configure bit addressing to be 0-15 or 1-16 addressing, and can also set the driver

to use 1 or 15 as the MSB (changing the bit referencing). For more information, refer to Addressing Options.

Note: Only addresses that are not used by the controller can be written.
