Koyo Driver Addressing
The current Koyo addressing formats work only for the DL series of PLCs.
The input / output tags addressed under the Koyo driver use the addressing system shown here. The simple format of prefacing the address with the register or bit type to be used is utilized. The limits on any actual addresses will depend on the configuration of the system and type of CPU used. Note that bits can be extracted for word addresses by adding a "/" separator followed by the bit number. For example:
R100/0 will read bit zero of the 8 bit data register R100.
Address Type | Data Type |
---|---|
X | Discrete Inputs |
Y | Discrete Outputs |
R | 8 Bit Data Registers |
CT | Counter Status Bits |
T | Timer Status Bits |
CTR or CNT | Counter Accumulated Values |
TMR | Timer Accumulated Values |
SEQ | Sequencers |
SR | Shift Registers |
ST or S | Stages |
V | Variable Memory |
GX | Global Inputs |
SP | Special Relays |
SC | Scratchpad |
D | Diagnostics |
Some typical addresses would use the address types listed above followed by the register or bit number. Such as:
X10, Y20, TMR100 or V4010
