Modbus CONNECTION RULES
- Install the modules in the DIN rail (120 max)
- Connect the remote modules using cables of an appropriate length. The following table shows cable length data:
– Bus length: maximum length of the Modbus network according to the Baud Rate. This is the length of the cables that connect the two farthest modules (see Diagram 1).
– Derivation length: maximum length of a derivation 2 m (see Diagram 1).
Diagram 1
| Bus length | Derivation length |
| 1200 m | 2 m |
For maximum performance, it is recommended to use special shielded cables, such as BELDEN 9841.
IDC10 CONNECTOR
Power supply and Modbus interface are available using the Seneca DIN rail bus, via the IDC10 rear connector, or the Z-PC-DINAL2-17.5 accessory.
Rear Connector (IDC 10)
The meaning of the various pins on the IDC10 connector is shown in the figure if you wish to supply signals directly via it.
SETTING THE DIP-SWITCHES
The position of the DIP-switches defines the Modbus communication parameters of the module: Address and Baud Rate
The following table shows the values of the Baud Rate and the Address according to the setting of the DIP switches:
| DIP-Switch status | |||||
| SW1 POSITION | BAUD RATE |
SW1 POSITION | ADDRESS | POSITION | TERMINATOR |
| 1 2 3 4 5 6 7 8 | 3 4 5 6 7 8 | 10 | |||

Note: When DIP switches 3 to 8 are OFF, the communication settings are taken from programming (EEPROM).
Note 2: The RS485 line must be terminated only at the ends of the communication line.
The settings of the dip-switches must be compatible with the settings on the registers.
The description of the registers is available in the USER MANUAL.
ELECTRICAL CONNECTIONS
Power supply:
The upper limits must not be exceeded in order to avoid serious damage to the module.
If the power supply source is not protected against overload, a safety fuse must be installed in the power supply line with a value suitable to what the situation requires.
Modbus RS485
Connection for RS485 communication using the MODBUS master system as an alternative to the Z-PC-DINx bus.
N.B.: The indication of the RS485 connection polarity is not standardized and in some devices may be inverted.
INPUTS
INPUT SETTINGS:
Default settings:
Input #1: 0 – 100 Hz (16BIT)
Input #2: 0 – 100 Hz (16BIT)
Input #3: 0 – 100 Hz (16BIT)
Input #4: 0 – 100 Hz (16BIT)
Input #5: 0 – 100 Hz (16BIT)
Input #5 can be set as a totalizer:
Input #5: 0 – 10 kHz (32BIT)
ATTENTION
The upper power supply limits must not be exceeded, as this might cause serious damage to the module. Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- a fuse with a MAX. rating of 0,5 A must be installed near the module.
- separate shielded cables from other cables used for power installations (inverters, motors, induction ovens, etc…).
- make sure that the module is not supplied with a supply voltage higher than that indicated in the technical specifications in order not to damage it.
