hello ,
i am new to github so please forgive me if i made any mistakes
i am curently facing a issue whenever i am trying to read data from plc its giving me the below error
my code is
import snap7 #import library snap7
from snap7.util import*
from snap7.types import*
import time #import library time
def ReadMemory(plc,byte,bit,datatype): #define read memory function
result = plc.read_area(areas['MK'],0,byte,datatype)
if datatype==S7WLBit:
return get_bool(result,0,1)
elif datatype==S7WLByte or datatype==S7WLWord:
return get_int(result,0)
elif datatype==S7WLReal:
return get_real(result,0)
elif datatype==S7WLDWord:
return get_dword(result,0)
else:
return None

def WriteMemory(plc, byte, bit, datatype, value): #define write memory function
result = plc.read_area(areas['MK'],0,byte,datatype)
if datatype==S7WLBit:
set_bool(result,0,bit,value)
elif datatype==S7WLByte or datatype==S7WLWord:
set_int(result,0,value)
elif datatype==S7WLReal:
set_real(result,0,value)
elif datatype==S7WLDWord:
set_dword(result,0,value)
plc.write_area(areas['MK'],0,byte,result)

IP = '192.168.0.1' #IP plc
RACK = 0 #RACK PLC
SLOT = 1 #SLOT PLC

plc = snap7.client.Client() #call snap7 client function
plc.connect(IP,RACK,SLOT) #connect to plc

state = plc.get_cpu_state() #read plc state run/stop/error
print(f'State:{state}') #print state plc
a = 0
b = 0
c = 0
while True:
#read memory
readbit = ReadMemory(plc,0,0,S7WLBit) #read m0.0
print('readbit:',readbit)
readword = ReadMemory(plc,10,0,S7WLWord) #read mw10
print('readbyte:',readword)
readreal = ReadMemory(plc,15,0,S7WLReal) #read md15
print('readreal:',readreal)
readDword = ReadMemory(plc,20,0,S7WLDWord) #read md20
print('readDword:',readDword)

a = a+1
b = b+2.4
c = c+10
#write memory
WriteMemory(plc,0,3,S7WLBit,True) #write m0.3 True
time.sleep(1) #delay 1 sec
WriteMemory(plc,0,3,S7WLBit,False) #wite m0.3 False
time.sleep(1) #delay 1 sec
WriteMemory(plc,30,0,S7WLWord,a) #write mw30 value from a variable
WriteMemory(plc,40,0,S7WLReal,b) #write md40 value from b variable
WriteMemory(plc,50,0,S7WLDWord,c) #wite md50 value from c variable

Typo here:
result = plc.read_area(areas['MK'],0,byte,datatype)

Should be Areas['MK'] not areas['MK'].

Try that. :)
