7 EtherNet/IP Connection Parameters Set
Connection parameters the gateway provides are as below:
a. Input bytes number Instance102, range 5~496 bytes, the default value is 496 bytes;
b. Output bytes number Instance 101, range 1~492 bytes, the default value is 492 bytes;
c. Config bytes Instance113, 10 bytes (fixed).
Input Instance 102 data length can be set in the software SST-EE-CFG, range 5~496 bytes, among them the
first 4 bytes is real-time frame header (reserved);
Output Instance101 data length can be set in the software SST-EE-CFG, range 1~492 bytes.
Take configuration parameters of RSLogix5000 as an example:
Notes: The “Size” (the bytes number that has been configured) in the above picture, is consistent with the
input/output bytes number of Instance which has been configured in the configuration software SST-EE-CFG). In
the above picture, “Size” is 62 (62x32/8=248) in the input bytes Instance102. Now, the relevant bytes number
should also be 248 in the configuration software.
