4.1.2 Host Issued Write Commands - MSTR Type 1
If the Global Data Control Mode is not enabled, the 1560-MBP
will not look to the Global Data Table to obtain the Control and
Reference values. In this mode, the Host PLC must execute a
write command (MSTR Type 1) to the 1560-MBP to register
addresses 40001 and 40002, per the following drawing, to
control the drive.
MSTR Type 1 Accessible Data Registers: The memory map for the registers
which a PLC programmer can access from the 1560-MBP using the MSTR
Type 1 command. Note that a write to the Read Only space between 40011
and 40100 will place an Error Code in the MBP Status register.

Parameter Register Space
This register space contains the parameter table from the
SCANport device. This paramaters are stored in their
numerical order (example):
40101 = Parameter #1
40102 = Parameter #2
The full length of this space is a function of the SCANport
device connected. Max size is 2000 parameters.

Chapter 4 — Programming Considerations
In the example (at the bottom of the previous page) the 1560-MBP
responding at Node 37 would retrieve its control and reference values
from the 8th and 9th words of the Global Data block. In the Host PLC we
have placed this data in registers 40418 and 40419, as this corresponds
to the 8th and 9th position in the Global Data packet.
