Binary parameter access provides a method of reading from and writing to single system parameters on the controller. Unlike binary data packets, binary parameter access uses the actual parameter number. There are no groups or masks.
A parameter access header consists of a Header ID ( 0x00 ) followed by a Packet ID code and a 2-byte parameter. The Packet ID codes for the different types of packets are shown below. The following pages define each of the packets in detail.
Packet ID Codes |
| |
Code | Packet Type | Description |
0x88 | Binary Get Long | Receive long integer from controller |
0x89 | Binary Set Long | Send long integer to controller |
0x8A | Binary Get Float | Receive Float value from controller |
0x8B | Binary Set Float | Send Float value to controller |
When using the Binary Parameter Access, the parameter is converted to hex. The parameter is a 2-byte value sent low-order byte first. Here are some examples:
