Variable Name Size/Type Description
Control[2] 1
16-bit Integer
Array Element
Holds the MBP_MSTR Block Error Status
A value will be placed in this register after the message has
completed, failed, or timed out.
0 = message completed successfully
Any non-zero value indicates an unsuccessful message
attempt. For details, see MBP_MSTR Error Codes
Control[3] 1
16-bit Integer
Array Element
Holds the length (number of 16-bit registers) to be sent or
requested by the MBP_MSTR Block.
Control[4] 1
16-bit Integer
Array Element
Holds MSTR operation-dependent information.
Typically, this will be used to hold the starting register
address in the target device where data will be written by a
write command or read by a read command.
Control[5] 1
16-bit Integer
Array Element
Holds MBP_MSTR Routing Register information.
Used to specify a message source node.
Most Significant Byte (MSB) = Source Node Address, which
could be the slot number of an NOE module or a Quantum
processors built-in Ethernet port.
Use a default value of 254 (16#FE00 hex) to use a
Quantum processor's built-in Ethernet port.
Least Significant Byte (LSB) = MBP on Ethernet
Transporter (MET) mapping index.
Use a default value of 0 to use a Quantum processor's built-
in Ethernet port.

IP address
Example: the value 192 for IP address 192.168.0.100
Control[7] 1
16-bit Integer
Array Element
Byte3, second octet of the ProLinx gateway destination IP
address
Example: the value 168 for IP address 192.168.0.100
Control[8] 1
16-bit Integer
Array Element
Byte2, third octet of the ProLinx gateway destination IP
address
Example: the value 0 for IP address 192.168.0.100
Control[9] 1
16-bit Integer
Array Element
Byte1, LSB last octet of the ProLinx gateway destination IP
address
Example: the value 100 for IP address 192.168.0.100
