4.2.3 Read Register
The Read Register command (003) is used to read data in up to 120
sequential registers. When initiated by the GATEWAY_CMD_OK@
function, this command will transfer 16Ćbit data from AutoMate
registers to the AutoMax RĆNet Processor module's AutoMate image
registers. Note that the AutoMate register number and the AutoMate
image register number must not contain a bit designation (e.g.,
2000.01).
When initiated by an AutoMate GETRNT instruction, the Read
Register command is sent to the AutoMax RĆNet module. The
AutoMax RĆNet module responds with values from the AutoMate
image area. To make data available to the GETRNT instruction, an
application task must first move it into the AutoMate image area.
4.2.4 Write Register
The Write Register command (004) is used to write data to up to 120
sequential registers. When initiated by the GATEWAY_CMD_OK@
function, this command will transfer 16Ćbit data from the AutoMax
RĆNet Processor module's AutoMate image registers to any legal
AutoMate registers. Note that the AutoMate register number and the
AutoMate image register number must not contain a bit designation.
When initiated by an AutoMate SNDRNT instruction, the Write
Register command is sent to the AutoMax RĆNet module. The
AutoMax RĆNet module writes the data into the AutoMate image area.
To use data sent by the SNDRNT instruction, an application task must
read it from the AutoMate image area.
4.2.5 Read Register List
The Read Register List command (013) is used by AutoMate to read
multiple nonĆsequential registers in the AutoMax RĆNet Processor
module's AutoMate image area up to a maximum of 120 registers.
This command cannot be initiated by the AutoMax RĆNet Processor.
4.2.6 Write Multiple Points
The Write Multiple Points command (014) is used by AutoMate to
write a 1" or 0" into specific bits or points within a number of
AutoMate image registers without affecting other bits in those
registers. A maximum of 40 registers can be written to per command.
This command cannot be initiated by the AutoMax RĆNet Processor.
4.2.7 Who Are You
The Who Are You (050) command is used by AutoMate to determine
what Processors are active on the network. This command cannot be
initiated by the AutoMax RĆNet Processor.
4.3 Data Update Rate
The data update rate (the time it takes to pass the token completely
around the network) is displayed in register 23 (current token time)
and register 24 (maximum token time). Refer to sections 4.1.1.13 and
4.1.1.14, respectively, for more information regarding these registers.
