Page 5: Theory Of Operation
THEORY OF OPERATION As part of the serial interface port license, a standard Modbus protocol is installed on the DeltaV PSIC prior to customization. The PSIC needs to be flash upgraded from the Modbus protocol to the Allen-Bradley protocol before operation. The Allen-Bradley serial driver implements DF1 protocol. - Page 6 Powerful Solutions for Digital Plants With the Allen-Bradley driver installed, the “Advanced” tab under port properties will allow selection of the configuration option for the port to act as a slave. This Allen-Bradley driver does not support slave functionality, so this configuration option is not valid. The Allen-Bradley driver supports PLC-5 Logical ASCII and binary addressing, and SLC5/XX Protected Typed Logical addressing.

SpecialData3 SpecialData4 Device And Dataset Configuration The following paragraphs discuss some attributes in the device and Dataset configuration: 4.2.1 Device Address: The device address attribute is located in the device configuration box under port. It is the PLC/SLC node address, not the 1785-KE or 1770-KF2 communication module address. This number is used by DeltaV to uniquely identify each PLC in the Data Highway Plus network. - Page 11 Powerful Solutions for Digital Plants affecting other bits in the same word. This command is not available under the SLC5/XX architecture. 4.2.3 DeviceDataType This attribute defines what type of transaction will be performed for the Dataset between the PSIC and the Allen-Bradley device Values from 0 to 11 are listed in the above table. They are briefly described below: MYNAH Technologies 504 Trade Center Blvd.
- Page 12 Powerful Solutions for Digital Plants Types 0 – 3 (Basic Commands): These are mainly for PLC-5 backward compatibility to older types of PLC with non-paged memory like PLC-2. The special data fields are not used during configuration. All data (16-bit integer or discrete) are written/read through the PLC-2 compatibility file. The memory address in PLC-5 is assigned with the communication module address.
- Page 13 Powerful Solutions for Digital Plants Types 5 (Ranged Transaction with ASCII addressing) and 9 (Ranged Transaction with binary addressing): Unlike Typed operations that automatically adjust the memory address to accommodate the defined element type, the Ranged operations use word address exclusively. performs consecutive memory word read and write.
- Page 14 For floating point values, the starting address refers to the register number and a 4 byte value is read/written. For all other tables, the starting address refers to the register number and a 2 byte value is read/written. Notes: 1. DeviceDataTypes 7 and 10 are only valid with file type 3 and output mode 1. 2.
