Python script error

[marcombar]

Hi all, I have a problem with running a python script. The script from the shell works correctly, while from Zabbix it gives me the error:

Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "Traceback (most recent call last):
File "/usr/lib/zabbix/externalscripts/PLC_UPS_modbus.py", line 4, in <module>
from pymodbus.client.sync import ModbusTcpClient
ImportError: No module named pymodbus.client.sync

The script is as follows:
__________________________________________________ ____________________
#! / Usr / bin / env python
import sys
from pymodbus.client.sync import ModbusTcpClient
from pprint import pprint

# area of the plc straight without crowding

bit_place = []
bit_place = [15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,0]

def readArea (ipaddress, area, bit):
client = ModbusTcpClient (ipaddress)
client.connect ()
request = client.read_holding_registers (int (area), 2, unit = 1)
value = '% s'% format (request.registers [0], '016b')
if bit == 'all':
pprint (value)
else:
print (value [bit_place [int (bit)]])

if __name__ == '__main__':

if len (sys.argv) == 4:
ipaddress = sys.argv [1]
area = sys.argv [2]
bit = sys.argv [3]
readArea (ipaddress, area, bit)
else:
#print u "" "requires 3 parameters (ipaddress, area, bit) \ t $" ""
print ("error")

If you run it from the terminal:

root @ stf-isonoe-01: / usr / lib / zabbix / externalscripts # ./PLC_UPS_modbus.py 172.22.1.130 10003 04
result: 0 (OK)

The item is configured in several ways, but all of them give an error (see attached photo).

Where is the mistake?
Thank you very much all.
