1. OUTLINE
PROFINET communication converter COM-ML [For SRZ] (hereafter called COM-ML) is
communication converter to connect the RKC module type controller SRZ to the PROFINET.
This chapter describes features, package contents, model code, system configuration, etc.
PROFINET
PROFINET is the Ethernet base industrial network standardized according to IEC 61158 and
IEC 61784. The COM-ML communication converter uses PROFINET IO and conforms to the RT
(Real-Time) communication.
Host communication
Data send/receive is possible between the converter and the host computer through RKC
communication (ANSI X3.28-1976 subcategories 2.5 and B1) or Modbus.
Function modules
Multi-zone temperature control system can be easily achieved by connecting functional modules
(Z-TIO, Z-DIO and Z-CT modules) of SRZ to COM-ML. The combination of COM-ML and
functional module of SRZ is called an SRZ unit.
Up to 30 function modules can be connected to one COM-ML.
