4 Remote I/O Master Communications
Allocation Procedures
Step 1: Set the CPU Unit to PROGRAM Mode.
Step 2: Set the Master Enable Switch to TRUE.
Make sure that master communications was disabled by checking to see if *_MstrEnblSta (Master
Function Enabled Status) is FALSE, and then set to TRUE the *_Sw1MstrEnblCmd (Master Enable
Switch) to enable master communications. Once you have turned this switch from OFF to ON, which
will enable the master, the system operates over the master whether the power supply is turned OFF
or ON.
Note Do not change the Master Enable Switch to TRUE unless master communications are
stopped. (If the Master Enable Switch is change to TRUE when master communications are
enabled, a Unit error will occur and a "C5" error will be displayed on the 7-segment indicator
on the front panel.)
Step 3: Set the Master User-set Allocations Setup Table
This table specifies the area and first word for each block and the area and first word for the Alloca-
tion Size Setup Table.
