When IP address (H) (first octet) through IP address (L) (fourth octet) are given as IP_H, IP_MH,
IP_ML and IP_L, the error conditions are described as follows:
IP_H ≤ 0 or IP_H = 127 or IP_H > 255
or IP_MH < 0 or IP_MH > 255
or IP_ML < 0 or IP_ML > 255
or IP_L ≤ 0 or IP_L ≥ 255
Check I/O parameter Nos. 132 to 135, 149 to 152, and 154 to 157, the IP address of connection
