MS{anynode},MI174 – MI175 (12 Bit A/D Transfer
MACRO IC Node & Servo Channel Address MI-Variables
Each MACRO IC (0 and 1) has its own set of these variables. Therefore, they are accessed through their
MACRO IC. These MI-Variables determine the servo channel transfer addresses. Most are read-only
variables and cannot be changed.
MS{anynode},MI176 MACRO IC Base Address
Range: $000000 - $00FFFF
Units: Modified 16-Axis MACRO Station Addresses
Default: $C080 for MACRO IC 0 and $C0C0 for MACRO IC 1
MS{anynode},MI177 MACRO IC Address for Node 14
Range: $000000 - $00FFFF
Units: Modified 16-Axis MACRO Station Addresses
Default: $C0B8 for MACRO IC 0 and $0 for MACRO IC 1 (Not used)
MS{anynode},MI178 MACRO IC Address for Node 15
Range: $000000 - $00FFFF
Units: Modified 16-Axis MACRO Station Addresses
Default: $C0BC for MACRO IC 0 and $C0FC for MACRO IC 1
MS{anynode},MI179 MACRO/SERVO IC #1 Base Address
Range: $000000 - $00FFFF
Units: Modified 16-Axis MACRO Station Addresses
Default: $8000 for MACRO IC 0 and $9000 for MACRO IC 1
This is the base address of the first SERVO IC attached to the MACRO IC.
