8.3 Communication performed in the JP1/IM system environment
When you monitor the system operation using JP1/IM, communication based on the TCP/IP protocol takes place between the hosts in the system, using port numbers and IP addresses. The port numbers used by JP1/IM and JP1/Base are registered in the services file automatically when the product is installed. For details about the port numbers registered at JP1/IM installation, see Appendix C. Port Numbers. For details about the port numbers registered at JP1/Base installation, see the appendixes in the JP1/Base User's Guide. For details about the concept of communication in JP1 series products, see the section on the communication protocol of JP1/Base in the overview chapter in the JP1/Base User's Guide.
