1. Modbus RTU
CP1L with V1000 and Celciux

2. Settings CP1L Serial Gateway Baudrate 9600 8 databits 1 stopit
Even parity

3. Settings Celciuxº
Use “CelciuX Technote 3C” Connecting CP1L to CelciuXº
Connect CelciuX with PC / CX-Thermo with the E58-CIFQ1 cable and
adjust the “Comm. Port B” settings (defaults are CompowayF, 9K6bps, 7-E-2)
Set to “Modbus, 9k6 and 8-E-1” to match the CP1L and V1000 settings
With V1000 the 8 and 1 are fixed, so then only 8E1 and 8O1 are possible

7. CP1L with V1000 and Celciuxº When connected you can use either:
CP1L’s “easy Modbus Master”
Make the settings in the memory area of the CP1L to read/write parameters from/to the V1000 and CelciuX (see next slide)
CP1L’s function blocks
V1000 settings must be Modbus
CelciuX settings must be CompowayF
The “mix” of protocols work!! CP1L doesn’t care and the slave do not listen to messages from each other
You can use CX-integrator to connect to the CelciuX and use CX-Thermo, the V1000 will give a comms error.

8. CP1L Easy Modbus Master to EJ1 (example)
Connecting EJ1
Must connect to port B
SW and -8 must be “off”
Select correct unit number of EJ1 in the host
Select PortB comm protocol in EJ1 = Modbus
Datalength must be 8
With parity none, stop = 2 bits
With parity Odd or Even, stop = 1 bit

Read PV from CelciuX
< Request PV
< Reply
> PV = 0050hex
50hex = 80’C (decimal)
< execute request bit
Response on Read PV
D32350: xx01 (slave adress =1)
D32351: xx03 (Function code = 3 = read)
D32352: (error code = 00 = normal end)
D32353: (number of response bytes = 5)
1=count, 2=data, 2=data
in this example it says or
4 bytes, 0050 (=80dec) and 0000 (=0)

READ PV
D32300 : xx01 (Slave number = 1)
(1 byte setting at Bit 7-0)
D32301: xx03
(Function code = 3 = Read)
