53MT6000 INSTRUCTION MANUAL
Database Editor 79
Set UP: This designates the data format transfer protocol. Clicking on the
"down arrow" reveals a list of three selections, these are [DDIA =
B293, DDIB = B459]:
8, 1, NO
8, 1, EVEN
8, 1, ODD
Network Address: This parameter may be required when using intermediate
communication adapters such as Allen Bradley KF2
Communications Modules.
Self Address: This is the 53MC5000 source address used in all messages to the
Allen Bradley. [DDIA = B670, DDIB = B646]
Set Up Error: This index number refers to a problem with the read or write setup
parameters [DDIA = B684, DDIB = B660]. These errors cause DDI
operation to halt.
0 = No error
1 = L-words to read greater then 32
2 = C-words to read greater than 64
3 = L-words to write greater than 32
4 = C-words to write greater than 64
5 = The write command is not 0 (Protected Write) or
8 (Unprotected write)
10 = Scan time is at 0
Scan Time (x100ms): This index number is used to specify the time period for the read
and write phases of the controller to PLC communications. Enter a
number from 1 to 255 (0.1 to 25.5 seconds). [DDIA = B685, DDIB =
B661]
Scan Overruns: This counter is incremented each time the read-write phases
exceed the specified scan time. If the counter is incrementing, the
communication transfer is not being completed in the allotted time.
The Scan Time should be increased. [DDIA = B686, DDIB = B662]
Unit Address - Read: This is the address of the PLC to be accessed. [DDIA = B664,
DDIB = B640]
Starting Memory
Address - Read: This is the beginning memory address for reading data from the
PLC. All subsequent memory locations are referenced from the
starting location as contiguous words of data. The data that is read
is mapped into the controller database in the exact same order. This
is a decimal number that is converted and stored as two bytes in the
controller database. [DDIA = B665 &B666, DDIB = B641 & B642]
