Too Many I/O Points Error Details

¿Qué significa A407.13 to A407.15 ?

These bits provide a 3-digit binary value indicating the specific cause of a 'Too Many I/O Points' error (A407.00 to A407.12). The CPU Unit operation will stop and the ERR/ALM indicator will light.

• 000 (0): Total I/O points configured exceed the CPU Unit's capacity
• 001 (1): Number of interrupt input points exceeds 32
• 100 (4): Number of Pulse I/O Modules exceeds the allowed limit
• 101 (5): Number of Racks exceeds the allowed limit
• 111 (7): Number of Units on a Rack exceeds the allowed limit

1. 1

   Read the binary value of A407.13 to A407.15 to identify the specific I/O configuration violation

2. 2

   If 000, reduce the total number of I/O points in the I/O Table (excluding Slave Racks)

3. 3

   If 001, reconfigure interrupt inputs to ensure no more than 32 are used

4. 4

   If 100, reduce the number of Pulse I/O Modules connected to the system

5. 5

   If 101, reduce the number of Expansion Racks used

6. 6

   If 111, redistribute units across multiple racks or reduce the total number of units on the affected rack
