SIMATIC S7 Ethernet 10 System Structure Overview The following table describes the basic system setup fo r connecting the target machine to Siemens S7-200/300/400 Series PLCs over a netwo rk.
SIMATIC S7 Ethernet 11 *2 PLC supports a maximum of 64 conn ections. Because 2 conn ecti ons are required for each target machine, one for Fetch and one for Write, the PLC can support up to 32 target machines. *3 The direct connection to the Ethern et Interface on th ese CP Us only supports the “OP Communication” type.
SIMATIC S7 Ethernet 12 Supported Device Addresses Overview The following tables list the device addre ss ranges you can enter from the Device Address keypad. For actual device address range s supported by the PLC, refer to the corresponding PLC manual.
SIMATIC S7 Ethernet 13 *6 Data blocks are created by the user. Available a ddresses depend on what the user has created. *7 PLC word addresses defined for integer, float, and string variab les mu st be even-numbered. i.e., IW5 is not a valid device address for an integer variable.
SIMATIC S7 Ethernet 14 *7 PLC word addresses defined for integer, float, and string variabl es must be even-numbered. i.e., IW 5 is not a valid device address for an integer variable. Must be either IW4 or IW6. *8 16-bit and 32-bit data , High and Low, refer to data as defi ned in the following example s.
SIMATIC S7 Ethernet 15 Consecutive Equipment Add resses Overview The following table lists the maximum number of consecutive addresses that can be read by each PLC. Refer to this table w hen using block transfers. Note : z To speed up data communicatio n, use consecutive variable addresses on the same panel screen.
SIMATIC S7 Ethernet 16 I/O Manager Configuration Overview The driver and equipment, which enab le communication between the target machine and the PLC, depends on the PLC type. Screen example of I/O Manager Configuration Note : z For informatio n on how to display the [New Driver] dialog box, see the online help.
SIMATIC S7 Ethernet 17 Equipment Configuration Overview To set up details about the communicati on process between the target machine and the PLC, use the [Equipment Configuration ] di alog box. For an overview of the driver and equipment settings, see Equ ipment Configuration .
