ACTION TYPE:
1. COMMAND – A new value written to these instructions will execute
the command.
2. DATA R/W – Reads the current value and will send a new value.
3. READ DATA – Reads the current value. Ignores any write attempt.
4. COMMAND DATA – Reads data that is stored in HMI. Stores written data in
HMI for retrieval when the related command is executed. E. g., the operator
writes to CHA, CHB, and CHC. The HMI will store the data, and the values
will be transmitted to the SMC only when the CH command is executed.
5. COMMAND/STATUS – Executes the command when a new value is written
to it, reads the current status.
6. Send 0/1 to Axis – Executes the command on the selected Axis.
7. BIT WRITE – Clears the configured Output bit if the written data is 0,
otherwise sets the bit.
“Reading” any COMMAND will set the item to 0, except as described in
Note 1, below.
Note 1: HX and XQ are commands that accept a line number (< 32767) as a data
input. It is recommended that these two commands be selected with Access set
to Read and Write, when declared as a variable. The driver will then set the
value of these to –1, so that the command will be executed every time a valid
line number is sent.
User Variables YP through YY are selectable. If more are needed, it is possible to use
one variable as an index, and another for the data. Use the data comparison functions of
the software to route the data properly. For example, VariableArray[YY] = YX, will
provide as many user variables as needed.
In many cases, a clever programmer might be able to use higher bits of the transferred
data word to indicate the source of the data in the lower bits.
For example, VariableArray[(YY & 0xFF000000)>>24] = YY & 0x00FFFFFF, will
allow 256 independent results of values less than hex 1000000 (decimal 16777216).
In either case, use “On Update” to transfer the proper values to the proper locations.
TCP Information
The G3 Ethernet Port must be manually configured to a fixed IP. When the Protocol is
selected, the SMC must be configured to its internal IP. The programmer may use the 232
port, with the IA command, to set that IP, code the IP in the SMC program, or use the
Boot P utility of the Yterm software.
