Chapter 5 Communication
Please make sure that you have read chapter 4 and fully understood the CME-PD01 installation.
5.1 PROFIBUS Address
CME-PD01 has two rotary switches to set the PROFIBUS address, the only way for user to set
the address. The address switches, ADDH and ADDL, allow user to set the address in a HEX
format. ADDH is used to set high 4 bits of address, and ADDL is used to set low 4 bits of address.
If both ADDH and ADDL are set to F, and CME-PD01 is power ON or re-power ON, then CME-
PD01 will enter the TEST mode, the SP LED and NET LED will be in steady orange.
Address Description
1..0x7D Valid PROFIBUS address
0 or 0x7E..0xFE Invalid PROFIBUS address
0xFF Enter TEST mode
NOTE
Setting changes via address switches will not effective when CME-PD01 is operating. This
means the setting changes will effective after CME-PD01 power re-boot. Please understand this
cold restart must be initiated by toggling the power to OFF and then ON.
