Simatic/TI 505 Ethernet Driver Help

Descriptions of the parameters are as follows:

l Port Number: This parameter specifies the port number that the remote device is configured to use. The

default port number is 1505.

l IP Protocol: This parameter specifies whether the driver should connect to the remote device using the

User Datagram Protocol (UDP) or Transfer Control Protocol (TCP). This driver requires Winsock V1.1 or

higher.

Note: If the Simatic 505-CP1434-TCP card is being used, then a UDP server job must also be set up if

using the UDP IP Protocol (or a TCP server job if using the TCP IP Protocol). It is recommended that the

TCP IP Protocol have retries set to a greater value than the default setting of 3.

l Request Size: This parameter specifies the number of bytes that may be requested from a device at one

time. To refine this driver's performance, configure the request size to one of the following settings: 32,

64, 128, or 250 bytes. The default value is 250 bytes.

505 Protocol

Descriptions of the parameters are as follows:

l 505 Protocol: This parameter specifies whether the driver should use CAMP or CAMP+Packed Task Code

Protocol when communicating with devices. When set to CAMP, the driver will only use the CAMP Memory

Transfer protocol. When set to CAMP+Packed Task Code, the driver will use Packed Task Code when

possible in addition to CAMP Memory Transfer. The default value is CAMP+Packed Task Code.

Note: CAMP+Packed Task Mode will be used for C, X, and Y registers when TI565 is checked.

l TI565: This option should be checked when using a 565 model PLC to access C, X, and Y registers. The

default value is unchecked. For more information, refer to Common Data Type Addressing.

Note 1: Some address types, strings, and arrays are not supported under the Packed Task Code Protocol. For

more information, refer to "Packed Task Code Protocol" in Common Data Type Addressing.

Note 2: For best performance when using CAMP+Packed Task Code, the number of task codes per scan on the

PLC should be set to the maximum number available, which is typically 8. If using TISOFT, this may be set using

Aux Function 19.
