# SLMP PLC Device Addressing Configuration

The Device Addressing is used to configure the PLC/MC device addresses and sizes of the various data blocks that will be communicated from the vision system to the Mitsubishi PLC/MC. The Device Type and size of the data blocks vary, depending on the Controller Type (Q/L Series or FX Series) defined in the Settings.

Setting | Description
--- | ---
Ndm Signal Block | Specifies the name (read-only) of the data block that will be communicated to or from the PLC/MC.
Selected Device | Specifies the PLC/MC device that will be used to read or write the data block. The available PLC/MC devices are as follows:
Device Name | Prefix | Bit/Word Based | Address Representation | Q/L Series | FX Series
--- | --- | --- | --- | --- | ---
Input Relay | X | Bit | Hex (Q/L Series)/Octal (FX Series) | X | X
Output Relay | Y | Bit | Hex (Q/L Series)/Octal (FX Series) | X | X
Internal Relay | M | Bit | Decimal | X | X
Latch Relay | L | Bit | Decimal | X |
Annunciator | F | Bit | Decimal | X |
Link Relay | B | Bit | Hex | X |
State Relay | S | Bit | Decimal |  | X
Data Register | D | Word | Decimal | X | X
Link Register | W | Word | Hex | X |
File Register | R | Word | Decimal | X | X
File Register Multiple Blocks | ZR | Word | Hex | X |
Timer | TN | Word | Decimal | X | X
Counter | CN | Word | Decimal | X | X
Offset | Specifies an offset within the device table used to read or write the data block. The offset value should be entered in decimal, hexadecimal or octal, depending on the Selected Device.
Size in Bits | Specifies the size of the data block that will be communicated with the PLC/MC. The size is expressed in units of PLC/MC "devices", and is configurable only for those data blocks that do not have a fixed size, or where the size is automatically set by the referenced Format PLC Input Buffer or Format PLC Output Buffer.
